The MacTighernan  DNA Test

McTernan / McTiernan / MacTiernan

The goal is to map all MacTighernans both genetically and geographically. With 137 tests completed, 3 TBR and 1 to have scores transferred, the DNA sampling in this test is random currently from 137 MacTighernans or very close surname variants from around the world that at the time of testing live in 13 countries on 5 continents with no correlation except the same surname or close variant and the same close proximity of origin in Cos Leitrim, Sligo, Roscommon and Cavan with a couple of outlyers. Like most Irish families, the deep time history of the MacTighernans is all but lost.

The DNA test is perhaps the only chance to begin to make any family connections as many of the MacTighernan families like a smaller scale of the larger Irish Diaspora have scattered to distant lands in the world and live there today. The spelling of the surname does not really matter as the historical spelling never seems to match the current spelling in many of the families so the Gaelic spelling of MacTighernan is used to cover all the variants of our surname including McKiernan. 

To date, almost all 137 tested MacTighernans that know their origins come from this small area in Connacht in NW Ireland shown in green on the map on the left, 450 square miles more or less with a few exceptions, Gus and Terry whose verbal family history states that their line is from Scotland and David (CN)'s verbal family history states that his family is from the Kilarney Lakes, Co Kerry area of Ireland.  Based on the DNA study at this point in time it appears that the origins of most MacTighernans, 89 out of 137 are in Co Leitrim. The Google earth satellite image that graphically shows the townland origin of each MacTighernan if known is at this web site: http://mctiernan.com/McTmaps.htm



While Leitrim is one county, it is historically divided into North and South Leitrim with Lough Allen being the dividing line. In South Leitrim from the mid 1500s, the Irish Clan way of life was under serious threat. An increasingly powerful English administration was slowly but surely extending its influence and dominion. In a visit to Mohill in 1540, the Saxons destroyed the Monaghan Franciscian Friary and beheaded the Prior and several of the Monks.   By 1590, the English government forces were actively routing the local clans. All MacTighernans in the DNA test from Leitrim come from north Leitrim with the exceptions of Michael-MH, Ed (NJ), [Scott (CO), Cathal, Sean-SF], Jim III and Charles whose family origins are in townlands in South Leitrim.

Philip O'Rorke, The O'Ruairc of Bréifne whose family were the past kings of Drumahaire in Co Leitrim has taken the DNA test. The O'Rorke DNA web site is  http://www.familytreedna.com/public/roark/. The O'Conor Don, Cathal Crovderg O'Conor, whose ancestrial home was Clonalis House, Co Roscommon and whose ancestors were the past high kings of all of Ireland for 150 years has also taken the DNA test. So far none of us genetically relate to either one. With the tests completed so far we 137 MacTighernans fall into 20 different, separate, distinct and unrelated genetic groups.

Genetic diversity equals age. The more diverse genetic make up of a population in a specific area, the older it is. In all the world, Africa has the most diverse genetic makeup. Ethiopia, the Horn of Africa has the most genetic diversity in all of Africa which is where the first humans gathered to exit and populate the rest of the world. Western Europe including Ireland has the least diverse genetic population of all areas on earth. So in Africa the population moved and in western Europe they did not, genetically speaking.

There is no way to know for certain what the total number is for distinct genetically separate MacTighernans on a worldwide basis. My research specifys about 483 individual MacTighernans worldwide. I am guessing that many are in the same family.  In 1659 only 4275 people lived in all of Co Leitrim of which MacTighernans were 38, 26 in north Leitrim and 12 in south Leitrim.  Mary Tiernan offers this web site for the Down Survey for a better understanding http://downsurvey.tcd.ie/.

The below is taken from the book the life and times of Sir Frederick Hamilton 1599--1647.  The Leitrim town of Manorhamilton is named after Sir Frederick, who was also known for his addicted hobby of hanging a Catholic a day.

In or about 1620 several Leitrim locals were given lands in James I plantation effort. A Mulmory MacTernan is listed as a lesser grantee during James I Plantation effort in Leitrim. In 1641, Mulmory MacTernan, of Lisnanorrus townland, chief of the clan, was a resident justice of the peace for Co Leitrim.  Some years earlier he was the Co. Leitrim Sheriff.  As such, he was an important man in the county also owning the neighboring townlands, Drumbrahade, Lisacoghil, Lisnanaw, Tullintowell and possibly Greaghnaglogh.  The 1847 Griffith's validation list possible descendents: Thomas McTernan in Lisnanorrus and James mcTernan in Greaghnaglogh.  The 1901 and 1911 census list a Thomas McTernan, 1871--, and his wife Mary, 1873--,  in Lisnanorrus with two children, John Francis, 1897--, and Anne, 1902--. 

The undertakers were listed as receiving the divided lands of The O'Rourke. Mulmory MacTernan is listed as receiving 500 acres of O'Rourke land which was at the lower end of the scale. The expectation was for the grantee to keep the local natives in check.  The grants to lesser sub chiefs [like MacTernan] were to help crush the power of the O'Rourkes once and for all.  The king took a higher percentage of the confiscated land in Leitrim as opposed to other counties as the Leitrim natives needed more civilization than the midlands.  In February 1642, Sir Frederick Hamilton sent a force of 80 horse and foot to relieve the protestants at Parke Castle. On their return to Sir Frederick's castle they were attacked by 1000 Irish rebels.  After a fierce battle the English won and killed 60 of the rebels.  Unfortunately, Mulmory MacTernan was one of the 60 killed.

Now this is the gospel truth, 375 years after Sir Frederick Hamilton killed Mulmory MacTernan in 1642, when he saw another McTiernan inside the ruins of his castle, namely myself, his ghost tried to kill me.  In November of 2017, I and my family were visiting Ireland, specifically that day, Manorhamilton.  We were touring the ruins of Sir Frederick Hamilton's castle and about 5 seconds after I turned the corner in the photo at left, the ghost of Sir Frederick launched a 200 lb. stone from the high castle keep falling away from the castle walls.  Strange after 375 years the rock fell just when a McTiernan was passing by.  He killed Mullimury but missed me.

North Leitrim's largest town, Manorhamilton was called "O'Rourke's little fields". It's name was from one of the most dreaded local rulers, Sir Frederick Hamilton who came to Manorhamilton from Scotland and founded a castle in 1638. He was the grandson of James II,  Earl of Arran. It was said that Sir Frederick was used as an example if you were trying to make Cromwell look good. He was to use the gallows in Manorhamilton daily, to hang a Catholic. One of his last and many acts of destruction was the burning of Carr Castle, a stronghold of the O'Rourkes at Glencar in 1641.

Lord Hamilton had invited the local chiefs to dine at his castle with the intention of killing them while they ate. As the time approached for the servants to do the deed, the old Irish piper providing the music for the feast played the song, "Make your visits short and far between". Too busy eating and drinking to get the hint, the local chiefs were killed by the servents. Lord Hamilton and his castle fell in 1652 when attacked by the Royalist Clanricard and Owen Roe O'Neill. As per Lorcan O'Runai in his book "From Rosclougher to Rooskey": Lord Hamilton escaped from his castle hiding in a group of women released by Owen. It is said that he shed tears as he paused on horseback to take a last look at his burning castle.

Unlinked and unproven but still a good chance, most likely our very early history falls under one of these three noted MacTighernans below.

Earlier in the 11th century two MacTighernan families were noted in Irish history as chiefs, Lord McTernan of Tullyhunco, Co Cavan and the McTernans of Co Fermanagh. Their lines may well be extent at this point in time. In recent history, at least since the famine years, most of the MacTighernans in Ireland are found in Co Leitrim. The historical family origins of the majority of the 137 DNA testers are in Co Leitrim. How we might connect to them or to each other is very difficult to prove as written records in Ireland usually only start at around the 1850s.

The McTernans of Co Fermanagh may have disappeared and there are no known descendants of the other three 19th century historically well known MacTighernan families from Rockfield and Tullyhunco listed below. The seat of the Tullyhunco MacTighernan family for many hundreds of years was Cruacan mic Tigearnain where The O'Rourke was inaugurated Prince of the Bréfny. It is now called Croaghan, lying six furlongs [3/4 mile] northerly of the village of Killeshandra in the barony of Tullyhunco in Co Cavan. The earliest entry in the annals on the MacTiernans is 1258 about a Magrath MacTiernan, chief of Teallach-Dunchadha who was slain by Donnell, son of Conor O'Rourke. The MacTighernan castle ruins are at this web site: http://mctiernan.com/castle.htm  In Irish history the Rockfield McTernans and the Heapstown MacTiernans were part of the landed gentry which translates to being well off being able to send the kids off to boarding schools.  One Rockfield son went to medical school in Paris and ended up a surgeon in HMS Naval service seeing action in America's War of 1812 in the Chesapeake Bay [near Baltimore, MD] in America and also being on the island of St. Helena helping to guard Napoleon when he passed.

According to John C. McTernan's recent book titled Sligo Families, vol II,  Leet's Directory (1812-1814) listed three McTernan 'seats' or residences, namely that of Con at Rockfield [noted above], James of Leonagh and Hugh [ T group baseline ] at Mount Allen in Co Roscommon whose family was originally from the Sweetwood Lower townland in Co Leitrim.  A diagram of the family links along with the connection to the O'Conors, http://mctiernan.com/3links.htm

A recumbent tombstone in Killargue's old cemetery behind the chapel bearing the family coat-of-arms, is inscribed with the names of Farrel McTernan, 1752--1818 and his wife Mary Dolan, 1752--1798. Farrel is the given name of the earliest known ancestor of Hugh McTiernan (Bos) family line who is in the T2 DNA Group.

The Chapel of Creevelea was the traditional burial place of the McTernans of Rockfield, Mount Allen and Heapstown [and Sheskin] where large recumbent flagstones mark their final resting places. In close proximity another memorial links the families of O'Rourke and McTernan and is inscribed as follows: Here lyeth the bodye of Hugh O'Roirk and Catherine McTernan who departed this life May 22, 1721. This is the mysterious gravestone that has the symbols of playing cards: heart, spade, diamond and club along with the etching of a cat which in O'Ruaric history is supposed to have awaken him from a nap in a pasture preventing him from being captured by enemies. The foot of the McTernan Achievement at left states: The McTernan coat of arms hereby illustrated is officially documented in Burke's General Armory. The original description of the Arms [at left] is as follows: Two lions pass., GU. When translated the Blazon also describes the original colors of McTernan Arms as: Ermine; two red lions walking on a field of caltraps. Caltraps were home-made 4 inch wooden spikes bound together like jacks in pick-up-jacks.  When running away from the Calvary you threw these over your shoulder and when a horse steeped on one the Calvary stopped and you got away.  Above the shield and helmet is the crest which is described as: A Red Griffin Standing, Green Wings Raised.

This info can be complex so please read the headers and footers in all the following grids to better understand it.   http://mctiernan.com/read.jpg

The 20 separate, distinct and different MacTighernan DNA groups start with the letter T which is just a naming convention as each of the DNA Groups are in all ways equal, none being more pure than the other.

The ancestors of the two McTernan families from Leonagh in Co Leitrim, Rory's from Sweetwood Lower in Co Leitrim, Heapstown, Co Sligo & Mountallen, Co Roscommon and mine from Sheskin, Co Leitrim all of whom are in the T Group are buried in the Abbey of Creevelea, Co Leitrim. Rory's earliest known ancestral home is in Sweetwood Lower, Co Leitrim and then in Mountallen Townland in Co Roscommon which has the date 1671 etched in the fire place mantle which implies the year of construction of their family home.  From Mount Allen, the family moved due to the cholera breakout to Heapstown, Co Sligo. 


John C. McTernan [T3a * photo at left], the well known Co Sligo arthur and retired Chief Librarian of Co Sligo in his book Sligo Families II writes that the Mount Allen / Heapstown McTernan family originally came from Sweetwood Lower, Co Leitrim and relate to the Leonagh, Sheskin and Rockfield McTernan families, see http://mctiernan.com/3links.htm. Three of these four families are buried at the Abbey of Creevelea with the Rockfield McTernans whose male line has become extent buried in their family vault at Brockley Cemetery, Parish of Lewisham, Kent, England.

This web site has the beginning of a very complex diagram of how the 2 McTernan families [Rockfield & Heapstown] relaate to each other and to the O'Connors of Sligo who are suppose to be part of the clan that were once the kings of all Ireland.  The Heapstown McTernans are in the T Group baseline.  http://mctiernan.com/3links.htm

Relationship of the DNA Groups to each other: The T and T3 Group baselines only have 16 out of 25 DYS markers that match. More than 1/3 of the markers do not match resulting in a 9 loci pattern mutation event difference. The T2 Group baseline has an 8 loci difference to the baselines of both the T Group and the T3 Group. Philip O'Rorke, The O'Ruairc of Bréifne has a 9 loci mutation event difference with the baselines of the T and the T2 Groups but only a 7 loci mutation event difference with the T3 Group baseline. The O'Conor Don has a 21 / 25 match to the T3a baseline. If you are in one DNA group you do not genetically relate to any MacTighernan in any other DNA Group

Our name may have been part of the inward migration of colonists and displaced people in the 17th & 18th centuries.  The native Irish names of North Leitrim previous to the 17th century were O'Rourke, MacClancy, MacKinnaue, O'Meehan, McMurrow, and MacGoldrick.  The O'Rourkes were the ruling family of the former kingdon of Breifne, MacClancy was the ancient tribal clan from Dartry in the north of the region and the MacKinnaues in the Lough Allen area;  the O'Meehams migrated from South Munster before the 11th century. The MacGoldricks were a clan of some consequence in and around that part of the region that adjoins Co Fermanagh. 

When the personal names in North Leitrim are examined we see there has been a great migration of people into the area of North Leitrim.  Some of the more prominent names in the area today are;  Rooney, McGowan, Kelly, McMorrow, Clancy, Connolly, McTiernan, McGloin, Feely and Dolan.  The most significant migration seems to have occured from Ulster.  Numerious northern families were displaced by the plantation of Ulster and after the Famous Diamond Fight in Armagh in 1793 many settling in Leitrim.  [above 2 paragraphs from; Glenfarne - A History]

The Great Unsolved MacTighernan Mysteries & Accomplishments


1. Locate Reverend Stephen's "copybook"   He was interested in historical and Gaelic matters for which he was made a member of the Royal Irish Academy in 1884. In addition, Rev. Stephen McTernan, 1811--1906, was a member of the Societe Generale in Paris, France for which he received an annual sum of money. Rev. Charles Comey, curate of Cloonclare, Manorhamilton uncovered Reverend Stephen's personal papers in 1907. They found the papers in St. Claire's Chapel in Manorhamilton. Cloonclare was in the ancient parish of Cloonloger, now included in the Catholic parish of Drumlease, Co. Leitrim. More on his personal papers which are called the "Copybook"  Finding this may be a key to unlocking the wider McTernan family history as Rev. Stephen kept this diary from childhood. Rev Stephen is my 1st cousin, 3 generations removed in the T Group.

2.  Understand the O'Rourke and McTernan connection in the Chapel of Creevelea as it was the traditional burial place of the McTernans of Rockfield, Mount Allen and Heapstown [and Sheskin] where large recumbent flagstones mark their last resting places. In close proximity another memorial links the families of O'Rourke and McTernan and is inscribed as follows: Here lyeth the bodye of Hugh O'Roirk and Catherine McTernan who departed this life May 22, 1721. This is the mysterious gravestone that has the symbols of playing cards, heart, spade, diamond and club along with the etching of a cat. Tie one of the future DNA testers to The O'Ruairc of Bréifne whose family were the past kings of Drumahaire in Co Leitrim

3. Tie one of the DNA testers to James McTernans, of the Rockfield McTernans a British naval surgeon who was in the squadron which protected St. Helena during the residence there of Napoleon, and was present on the island at the death of that distinguished, but unfortunate monarch in 1821. James was also the surgeon on a British warship in the Chesapeake Bay in the War of 1812. In historical documents, the Rockfield McTernans and the Heapstown McTernans [Rory's line in the T Group baseline] are called kinsmen and are related.

4. Understand the meaning of the 4,000-year-old Cairn on Rory's Heapstown family estate. What might be the connection to Rory's McTernan family who are in the T Group baseline.

5. The McTernan School: in Waterbury, CT.  In 2005, St. Margaret's-McTernan school changed its name to Chase Collegiate School. The new name honors the Chase family, which helped to found both St. Margaret's and the McTernan School. Charles McTernan from Foxbourgh, MA founded the school. A male line may descend from Charles' uncle, Patrick, 1863--, who was born in Boston. Charles' son Donald married and lived in France having two daughters. This family originally immigrated to the Boston area from Co Leitrim. Long shot for DNA match.

6. Jane Aloyaia McTernan, 1888--, born in Calcutta station, Bengal, India. To which DNA family does she belong.

7. Thomas McTiernan, 1883--1893, died at 10 years old at the army station of Mount Abu which is a popular hill station in the Aravalli Range in Sirohi district of Rajasthan state in western India near the border with Gujarat.  There is no mention of his parents in records.

8. Bernardette McTiernan, 1890--1893, most likely the sister of Thomas above. Died at the army station of Mount Abu which is a popular hill station in the Aravalli Range in Sirohi district of Rajasthan state in western India near the border with Gujarat. There is no mention of her parents in records.

9. Whereabouts of the McTernan Stone, an excessively heavy round stone thrown by Thomas McTernan known as Long Tom from Ardvoley, the grandfather of John-Rev in the T Group baseline. The stone thereafter was known as the McTernan Stone. This Stone lies now in the area of Killavoggy.

10. Tirmactiernan, Co. Leitrim on the banks of the Shannon/Erne canal system in South Leitrim. About 7.1 KM from Carrick on Shannon. Why was it named Tirmactiernan and what if any connection to any in the DNA test?

11. What might be our connection to Rathmactiernane, a townland in Killoran parish, Co Sligo listed in the Hearth roll of 1665 with Cahill McTanist?

12. A horse by the name of MacTiernan was racing in Dublin for the 2010 to 2012 season. He is running well, previously owned by Christine Kiernan. Why did she name the horse MacTiernan?

13. Cathal Mac Tigernan was King of West Connacht... died 1059... which means he predates the O'Rourkes. �ed in Gai Bernaig, King of Connacht from 1056 to 1067, had invaded and conquered Maigh Seóla in 1051, blinding its king. Cathal mac Tigernán is the next ruler of the kingdom recorded upon his death in 1049.

14. Origin of the 3 ring forts in the townland of Listernan, Co Cavan and why the name which in Gaelic means Ternan's fort?

15. We are supposed to descend from the O'Rourks past kings of Drumahaire & the O'Conor, past kings of Ireland. So far none of the MacTighernans genetically match either The O'Ruairc or The O'Conor Don Chieftains, but the T Group baseline is a perfect match to Michael O'Rourke.

16. The unfinished list of all MacTiernans who were killed or served in their country's armed services in the many wars for Freedom starting with the Leitrim Plantation Wars and ending with WW II, http://mctiernan.com/mwardead.htm 

17. Edward W. L. McTiernan from Worcester, MA had a top 10 finish in the 1909 Boston Marathon (#9) See 1909 & 1911 results at https://www.athlinks.com/event/20238/results/Event/606309/Course/919125/Entry/279059842   In 1908, E.L. McTiernan representing Worcester, MA ran in the Brockton Fair Marathon, starting in Boston, on Exeter Street, ending in Brockton, MA at the fairgrounds. If you look at the attached clipping, there is an Ed L. McTiernan of Worcester listed under the 1 Mile and 3 Mile runs. This is Edward William Lane McTIernan of Worcester, 5-29-1880--1955. Edward was the son of Thomas McTiernan and Catherine Lane, both of Ireland, both immigrating to the US and died in Worcester, Massachusetts. Edward worked for the streets department in Worcester. This is Edward William Lane McTIernan of Worcester, 5-29-1880--1955. Edward and his 6 children are in the T3 DNA Group baseline because of his relationship to Leo McTiernan and Jim-MA.

18. Potential but undocumented link of the Heapstown and Rockfield McTernans to the Sligo O'Conors, past kings of Ireland http://mctiernan.com/3links.htm

19. The MacTier Championship Cup, info supplied by Mike McTiernan of Canada. Most likely the cup is named after a MacTiernan but additional research needs to be done to trace the origin of the name of the cup. The MacTier Cup established in 1998 is awarded to the championship team for winning the top senior men's rugby league in Canada.  Since 2009 the cup has been awarded to the winners of the Canidian Rugby Championship (CRC).  Since the inception of the CRC, the Ontario Blues have won the cup 6 times, the BC Bears have won 2 times, while the Prairie Wolf Pack and the Atlantic Rock both winning the cup 1 time.

Solved or achieved so far


20.  The McTiernan Seat since 1991 is an engraved bench in front of The 300 year old Powerscourt Arms Hotel in Co Wicklow  http://mctiernan.com/McTseat.htm The hotel was owned by Charlie McTernan, 1955-, until 2008 who is in the T2 DNA Group

21. The pamphlet written in 1845 by James MacTernan, <1815--1855, of the Mount Allen [Co Roscommon] McTernans that settled at Heapstown, in Co. Sligo entitled: "An Address to my Fellow Countrymen", in which James claimed descent from Tiernan O'Rourke, Prince of Breffni. Found by John C. McTernan.  This James McTernan also invented a new breed of horse called the Buckshot Chestnut. This is Rory MacTiernan's family in the T Group baseline.

22. The McTernan Street in Cambridge, MA, USA formerly Lake St. right outside of County Boston, named after WW II veteran, William Francis, -1944 . This is Myles McTernan's family: Te DNA Group

23. McTernan Road, Tinderry, NSW, Australia 2626: is named after the pioneering McTernan family of the area, descending from Hugh and Mary McTernan of Michelago of which Scott (AU) & Richard descend in the Ta DNA Group

24. Origin of McTernan Place, Worrigee, NSW, Australia 2540: is probably named after Barney McTernan [below], Hugh's son who lived down there and had a stagecoach business of which Scott (AU) & Richard descend in the Ta DNA Group

25. Barney McTernan, being one of the stagecoach founders, is now a major character in the book, "Coachmen of the Nowra District" in Australia. Scott (AU), Margaret & Richard in the Ta DNA Group relate to Barney.

26.  Gwladys McTernan Park, named after the mother of Scott-(AU), David, Grant and Richard in the Ta DNA Group, a park in Naracoorte, South Australia, Australia,  RIP

28.  McTiernan Way, a road in downtown Minto named on 9-2-2013 by the Village of Minto, New Brunswick, Canada after the long history of the family in fire prevention. This is Michael (CN)'s family in the T DNA Group.

29. Bartholemew E. McTiernan, 12-11-1877--12-6-1917, born and died in Halifax, Nova Scotia, Canada.  Bartholemew, his mother Margaret Gilroy and his wife Frances Caroline Gough were all killed in the famous Halifax explosion of 12-6-1917 which was and still is the largest man-made explosion after the atom bomb. Bartholemew is the great grand uncle of Greg McTiernan in the T2 DNA Group.

30. Lac McTiernan, a lake in Quebec, Canada, a 7 hour drive north of Ottawa and 5 hours north of Montreal. Lac McTiernan was named after William McTiernan born in Bryson, Canada. He worked for the Canadian International Paper Company in the early 1930s. To find out more about the man and his father, David McTiernan, both worked in the back country of Gatineau River, read the following book, particularly chapters 14 and 15, Crawford, Venetia, et Gunda Lambton. The Wildest Rivers -- the Oldest Hills; Tales of the Gatineau and Pontic, Maitland, Ontario. Canadian International Paper Company may have been bought by E. B. Eddy Company.  The family had a home in the Mason Lumber camp operated by the E. B. Eddy Company. 

A second historical opinion on "McTiernan lake" in the Gatineau hills which may not necessarily be named after a man that lived in Bryson by the name of William McTiernan, as Venetia Crawford explains in her book. William was the 2nd cousin, 2 generations removed of Thomas John McTiernan. Tom, was born and raised in Bryson, Quebec, but this "McTiernan lac" was named by him as a joke!

Tom worked in cartography for Energy, Mines and Resources for 35 years. In the late 70s he and his buddy Dan Lacelle came across quite a few "un-named" lakes in the Gatineau's. They thought it would be funny to name some lakes after themselves. I would have probably believed Venetia Crawford's story if I would not have found this pamphlet on the internet. Now - what are the chances that this hunting and fishing lodge is situated on the McTiernan and Lacelle lakes? Tom and his buddy Dan (and probably another 5 or 6 guys) used to go fishing together all the time in those days. However, it is a surprise that the names stayed and that these lakes are now known as the McTiernan and Lacelle lakes. The Lac some time ago. This is Maggie's & Thomas' family in the T Group.

31. McTernan Colour of the Year  This award is conveyed in honour of Irene McTernan, former Edinburgh University Sports Union Administrator (1980-2011), and awarded to the most outstanding individual for exceptional and sustained service to the organization, delivery and/or administration of a University Sports Club or EU Sports Union.  Colours are approved by the Blues and Colours Committee This award is confined to the University of Edinburgh students and was introduced in 2011 to mark the retirement of Mrs McTernan after 31 years of dedicated service to EU Sports Union. Her husband, Allen is in the T DNA Group baseline.

32.

38.  The Barr football team based in Co Cork instated a Championship Cup called the Kevin McTernan Cup for the Senior A Football competition named after the brilliant goalkeeper who was one of the great goalies in history.  It commemorates the great St Finbarr’s player, selector, and club stalwart, who passed away in October, 2017, and is fondly remembered out Togher direction. The Barr's great Kevin McTernan will be honoured when Mallow face Éire Óg     https://www.echolive.ie/corksport/arid-40317260.html


39. Gene McTiernan of the Scranton Pennsylvania McTiernans has written a book, "Black Veins Green Blood" on his immigrant Irish ancestors and how difficult it was for them working in the infamous Scranton coal mines.  In the early 1900s, the Scranton criminal courts hung about 20 immigrant Irish coal miners for some made up reason.  The solid belief at the time was they were hung because they all belonged to the infamous Molly McGuires.  Gene is in the baseline of the T DNA Group.

40. Thady McTernan was chairman of the writing group that produced the Local [Leitrim area]  history of the GAA and on the Editorial team.  Thady himself wrote a substantial part of the history.  In the past, Thady  won a Leitrim Senior Club football championship with Glencar Manorhamilton Club in 1977 playing at No 6 - centre half back.  He was awarded Leitrim Senior Club player of the year in 1989 and also won a Leinster Junior Rugby Towns Cup medal in 1975 playing with Portarlington at full back.

If anyone has any information on any of the unsolved mysteries listed above, please let me know by email:  michael@mctiernan.com  

The McTiernans haven't held tenaciously to their family name over centuries sometimes under duress if it did not mean something of real value to them. A legitimacy to their culture and land that stretched back into the distant past to an ancestral line. The Scribe O' Clery in his genealogies refers to two families of Mc Tiernans of North Leitrim, the Clann Tiarnain Bunnaidhe that is the McTiernans of the Bonnet (Drumahaire) and the Clann Tiarnain na Caraha or the McTiernans of Corry (between Drumkerran and Lough Allen) could this explain at least two of the main groups? There is also a possibility that some of those in groups of their own represent the last survivors of the true McTiernan lineage and that the 3 main groups are very successful interlopers? courtesy of Austin McTiernan who is in the baseline of the T3 DNA Group.

The "Great Frost" of 1740-41, Bliain an Áir, or Year of Slaughter, was a period of unusually cold weather that lasted from around December 1739 to September 1741, it was an event that affected the whole of Europe, though it seemed to have its worst effects in Ireland.  Deep frosts only occurred during the winter months, but there was little real respite afterwards as the spring and summer weather was unusually cold and dry leading to the death of livestock and the failure of crops, and therefore an inability to prepare for the second unusally cold winter.  Records are scant and the population size only an estimate, guesses as to the loss of life through starvation at this period are 38% of the population.

DNA Scoring


While each DNA Group is of equal standing, there are 3 main DNA Groups, the T Group with 47, the T2 Group with 31 and the T3 Group with 21. Each group's baseline is where all in that group started.  The baselines of the 20 distinct DNA groups form automatically when 2 or more MacTighernans genetically match each other perfectly, 25 / 25 then they become the baseline of that specific group.  Matches of 23 or 24 out of 25 markers are in that group just not in the baseline.  So there are 2 sets of MacTighernans in each of the 20 DNA Groups, the baselines which are made up of perfect match of 25 out of 25 markers and the others that match the baseline 23 or 24 out of 25 markers.   To date, there are 13 distinct DNA Groups that have only one person in each group with the other 8 having multiple members.

Y25: Distance 1: 24 / 25 Probability of a close relationship is very high. You share the same surname (or a variant) with another male [and close proximity of origin] you mismatch by only one 'point' on only one marker. For most closely related and same surnamed individuals, the mismatch markers are usually either DYS 439 or DYS 385 A, 385 B,389-1 and 389-2 from our first panel of 12 markers, and on the following from the second panel of 13 markers: DYS #'s 458 459 a 459b 449, 464 a-d, which have shown themselves to move most rapidly.

Y25: Distance 2: 23 / 25 Probably related. You share the same surname (or a variant) with another male [and close proximity of origin] and you mismatch by two 'points' among the 25 markers tested. The probability of a close relationship is good, however your results show mutations, hence more time between you and other MacTighernans.

Y25: Distance 3: 22 / 25 Probably not related. You share the same surname (or a variant) but are off by 3 'points' or 3 locations on the 25 markers tested.  The following 2 charts show matches that are close but yet still outside of the threshold to match.

Y37: test:  A 33 or better out of 37 markers says you are in the same DNA group.

Above numbers for perfect match of 25 / 25 are in red background - for their specific DNA groups, the red +  and  green + sign above means the grouped individuals are relate.  Gene who is in the T Group is an exception as his 3 mutations occurred in only one locus and is considered a radical mutation but is still listed in the T Group.  Mark, Martin & Nick may relate as the 3 families are from the townland of Leonagh. Peter McTiernan of Canada is related to Michael (CN). Turner Bluechel through his maternal line is related to Rory and his sister Alannah.

If you look at the attached clipping there is an Ed L. McTiernan of Worcester listed under the 1 Mile and 3 Mile runs. This is Edward William Lane McTIernan of Worcester, 5-29-1880--.  Edward was the son of Thomas McTIernan and Catherine Lane, both of Ireland, both immigrated to the US and died in Massachusetts. Edward worked for the streets department in Worcester.  If you look at the attached clipping there is an Ed L.

Ancestors in the light colored row in the above grid were born c. 1800. Michael's house in Knox.  My late father John, 1911-1980,  planted many trees on the entrance/laneway in his youth, they are still there and give a lovely memory to his life.  The Townland of Knox is located in the R/C parish of Aughawillan, it borders the Townland of Aughawillan and Glebe. It is located roughly 3 miles from the village of Bawnboy in Co. Cavan, just over the county bridge. This road leads on towards Garadice and on to Ballinamore.  A ** in the above grid are a perfect DNA match to each other. * = immigrant

Warren McTernan is the sole McTernan in the T4 DNA group and is a 5 out of 25 marker match with the T Group and a 7 out of 25 with the T3 Group.  A 22 / 25 match or less in the previous grids most likely means no common genetic ancestor or the common ancestor is well beyond 2000 years or 70 generations back in time, as in T Group baseline compared to the T3 Group baseline which is a 16 / 25 match. Surnames came into existence in the year 1120 more or less.

The symbol "<" is an event that occurred before that year and a ">" is an event that occurred after that year, e.g. <1800 means born before 1800

Any female in the above grid must have a male relative with the surname of MacTighernan take the DNA test.

Gwen Brogdon's McTernan line is from the townlands of Killavoggy and Sweetwood Lower in Co Leitrim. Those two townlands were mentioned in the last Will of James McTernan of Heapstown and Mountallen, the ancestor of Rory MacTiernan. John-Rev's line comes from Killavoggy also. The latitude N 54.09.00 is the line running east to west along the north shore of Lough Allen in Co Leitrim.

The origins of the MacTighernans that know their townland of origin are between the latitudes of N 53.48.35 to N 54.19.50 and the longitudes of W 7.06.20 to W 8.43.48. The Geographic map showing the townland locations by longitude and latitude is at: http://mctiernan.com/McTmaps.htm The specific location in longitude and latitude of known townlands is detailed on this web site along with some early MacTighernan history: http://mctiernan.com/location.htm

This web site gives a very good view of the wider Irish DNA studies for 1750 Irish families. http://www.familytreedna.com/public/IrelandHeritage

The MacTighernan castle ruins is at this web site: http://mctiernan.com/castle.htm

A recent study by Brian Mcvoy was conducted at Trinity College Dublin, Ireland, which found that a striking percent of men in Ireland (and quite a few in Scotland) share the same Y chromosome, suggesting that the 5th-century warlord known as "Niall of the Nine Hostages" may be the ancestor of one in 12 Irishmen. Niall established a dynasty of powerful chieftains that dominated the island for six centuries. The T3 Group baseline matches Niall's DNA 23 / 25 so they would descend from Niall, his uncle, his cousin or his brother. The remaining DNA groups in the MacTighernan study are not even close. Details are at this web site: http://www.familytreedna.com/matchnialltest.html

Several of the most recent MacTighernans tested have scored a higher number of mutations than previous testers, i.e. Gus in the T3b Group & Ed (NJ) in the T3c Group and Michael (Eng) in the T2 Group. Michael (Eng) had a 3 step mutation in locus 25 which is very unusual but loci 21 - 25 mutate more frequently than others. The problem here is that the last four loci have a different way of being tested. What looks like individual mutations can and most often are repeat mutations. This poses the problem of how to score the test and then secondarily how we relate to each other. FamilytreeDNA has published a web site that is based on mutation event differences which is a combination of both differences in loci and differences in mutations.

The mutation event difference takes into account false repeats in loci 464a-d that look like mutations but aren't. Michael (Eng)'s has a 3 loci difference with a total of 5 mutations from the T2 baseline. Off the FTdna web site Michael (Eng) shows an mutation event difference of 2 to his T2 baseline not a difference of 3 loci or 5 mutations. All but one of Michael (Eng)'s mutation activity is in the last 4 loci [464a-d] which is the most confusing to score. So I have changed all our scores on how we match up and relate to each other to reflect what the FTdna lab test site says they are. However, the raw scores have not been altered, being listed exactly as they have been reported.

This indicates that the MacTighernan testers have fallen into 20 unrelated, separate and distinct DNA groups that do not genetically relate. This is based on recent studies, where the FTdna lab now says that if you have a 2 mutation event difference [23/25] you still relate and the probability of a close relationship is good, however the results show mutations and therefore more time has elapsed between the common ancestor for yourself and the others that you match 23 / 25 or better. If your have a 3 mutation event difference [22/25] you probably do not relate and are outside of the closest DNA group. Both Scott (AU) and Gene are 3 event mutations off the T Group baseline. Scott (AU)'s 3 event mutations are spread over 3 different loci. Gene's on the other hand are all in one locus, locus # 1. Based on this and the lab's opinion that it is a radical mutation Gene is listed in the T Group whereas Scott (AU) is not. Scott (AU) forms his own separate DNA Group, Ta which is one of the 20 DNA groups.  Dan-W has 3 mutations off the T2 Group baseline but still is listed in the T2 group due to a 24 / 25 match with Jim-P who is in the T2 DNA Group.  Colin has a 3 event mutation off the T Group baseline and therefore forms his own DNA group, Tf.  Colin matches Mike-UK in the T Group  23 / 25.  JohnL has a 22 / 25 match to the T3d baseline but he is related to Thady and to Sean who are in the T3d  baseline.

Chris McTurnan's scores are off 4 from the T Group baseline which genetically puts him outside of the T Group baseline. However, Chris does match Douglas (CN) 23 / 25 which means that he and Douglas (CN) genetically relate. Douglas (CN) is in the T Group and Chris's 4 mutations are among the 13 that have the highest frequency rate. So Chris may in fact be closer to the T Group baseline than the scores suggest but that has to be better understood. Being consistent until more is known.

The below grid has the raw test scores. The terms locus [loci is the plural of locus] and DYS all pretty much mean the same thing. I would just look at them as categories. DYS stands for: D = DNA, Y = Y-chromosome, S = (unique) segment. The DYS numbering scheme (e.g. DYS390, DYS394) for the Y-STR haplotype loci is controlled and administered by an international standards body called HUGO Human Gene Nomenclature Committee based at University College, London. DYS is the scientific allele number.

Each tester's scores are valid and differences are only considered mutations when contrasted to the baseline of their closest DNA group. As an example all testers that are listed as T + 1 or T + 2 are in the T Group but show mutations off of the T Group baseline by one or two. While the Ta, Tb, Td & Te testers are outside of the T Group baseline range and in their own specific group their mutations are still compared to the T Group baseline. The T3a through the T3e groups are outside the T3 Group baseline range as well and their mutations are also shown off the T3 Group baseline. All testers in the T2 Group likewise show mutations against the T2 Group baseline.  The T4 Group stands alone. 

Each individual's test results are matched and compared to the baseline of their closest specific DNA group and all the other MacTighernans. Those that have a perfect match i.e. 25 / 25 in their specific DNA group become part of the baseline of their DNA group. At this time 12 of the 20 DNA groups have only one individual. Eoghan and Jim (NJ) both in the baseline of the T3 Group match each other on the 37 marker test, 36 / 37 which means they closely relate.

As stated earlier my goal is to map the genetic and geographic origins of all MacTighernans. If you are a close genetic match, 23 or 24 out of 25 markers with another MacTighernan in your DNA group you may have a lot of work to do to find the common ancestor but still you are on the right path. Also, the remaining question in our DNA test group is if one of us is off a specific baseline by 3 or 4 mutations or rather mutation events which implies that you are in a whole separate and distinct DNA group and you do not genetically relate to that baseline or your common ancestor is well beyond 2000 years or 70 generations back in time then that leaves the question of how we all ended up with identical surnames, if surnames only began in the year 1120. A guess is that way back in time before surnames came into use there existed in or around Cos Leitrim, Roscommon, Sligo or Cavan a tribe or clan whose leader was called MacTighernan.

In Gaelic, MacTighernan means "son of Lord". When surnames first started about 1120 all the male warriors in the clan might have just taken the chief's name for themselves which might be a reasonable explanation or guess as to how we all ended up with 20  different genetic groups from one small area of Connacht, Ireland all with the same surname or close variant.

Scores
MacTighernan actual raw test scores for the 20 DNA groups
Each of the groups are in a different color. Single step mutations off a baseline in the below grid are in red ( ) and 2 or 3 step mutations  are in dark blue [ ] The testers in the left column that are the baselines for each of their individual 20 DNA groups have a light red background
These are raw scores compared to the baseline of the 3 major groups, e.g. Te Group compared to the T Group, event mutations differences may be less than raw scores

Scores----MacTighernan actual raw test scores for the 20 DNA groups
Each of the groups are in a different color. Single step mutations off a baseline in the below grid are in red ( ) and 2 or 3 step mutations are in dark blue [ ] The testers in the left column that are the baselines for each of their individual 20 DNA groups have a light red background
These are raw scores compared to the baseline of the 3 major groups, e.g. Te Group compared to the T Group, event mutations differences may be less than raw scores

In Irish history it was written c. 1100s in the Annals of the Four Masters that the MacTighernans descend from both The O'Rourkes who were kings of Drumahaire and The O'Conors, who were past high kings of Ireland. However so far none of us that have been tested relate to the O'Ruairc line or the O'Conor line.  Philip O'Rorke (kit 2099) is The O'Ruairc of Bréifne. The O'Rourkes in Russia. Both Philip's test scores and Cathal Crovderg O'Conor are beyond the threshold of genetically relating to any of the  MacTighernan DNA groups. In the future there may be a MacTighernan that is a match with Philip or the O'Conor's. The O'Conor family has started its own DNA test that is found at http://www.worldfamilies.net/surnames/c/conner/results.html

This site for the DNA rules of the road and tells how an individual that is not a MacTighernan might have a DNA match but still not be related: http://mctiernan.com/dnarules.htm

The results from a search of the Haplogroup database not only provides information about our deep ancestral history, but the outcome can also be used to analyze Y Chromosome results. Since the Haplogroups are the branches, and the Haplotypes are the leaves of the tree, if any of the MacTighernans belong to different branches, no matter how close their Y DNA test results were, the individuals are not related. So far with the exception of Warren we are all on the same branch. Fifth teen  of the separate MacTighernan DNA Groups, and Philip O'Rorke fall into the larger DNA group called the Haplogroup R-M269 (old R1b) which is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. The R-M269 (old R1b) lineage is also the haplogroup containing the Atlantic modal haplotype.  Warren is in the T4 DNA group and forms the 16th DNA group.  Rather than the R-M269 (old R1b) Haplogroup Warren is in the Q Haplogroup.

The R1b Haplogroup is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia and Central Africa. The clade is also present at lower frequencies throughout Eastern Europe, Western Asia,  as well as parts of North Africa and Central Asia. The oldest human remains found with R1b so far are:

  • an individual known as Villabruna 1, who lived circa 14,000 years BP and reportedly belonged to R1b1a

  • a male commonly referred to as the "Samara hunter-gatherer", who lived approximately 7,000 BP in the Volga River area, who carried R1b1

We MacTighernans may have overcome the haplogroup effect by accident by having all the testers with the same surname and almost all originating from the same small 450 sq. mile area in Connacht [Cos. Sligo, Leitrim and Cavan] in Ireland. While our test was really random, we may have covered the problem of the haplogroup by those 2 conditions. Even though the origin of everyone's surname is 1120 more or less, 3 mutations or rather mutation event differences from the closest group's baseline means that you are most likely not related. This is a general rule based on where the understanding of mutation activity is at this point in time. Gene and Scott (AU) both scored 22 / 25 with the T Group baseline. Scott (AU)'s 3 mutations are spread over 3 different loci [markers] and Gene's are all in one locus. Gene's had what is called a radical mutation and hence is still included in the T Group due to his radical mutation of 3, only in locus #1. Scott (AU)'s 3 mutations are spread over 3 different loci and hence he forms his own separate DNA group Ta which is one of the 20 DNA Group baselines. JohnL is a 22 / 25 match to the T3d baseline but is related to Thady and  to Sean who is in the T3d baseline. A match of 23 / 25 or better with one of the 20 DNA groups means you genetically relate to that group.

The scores above are directly from the lab's web site. Locus 22 through and including locus 25 which is DYS 464 a-d have the following characteristics and are why the FTdna web site is used to match our test results by mutation event differences vs specific mutations or loci [category] differences.

DYS 464 was discovered at the University of Arizona by Dr. Alan Redd. This highly volatile (fast mutating) marker is included in the test to help show changes even within family groups that are closely related. DYS 464 is replicated 4 times in 98.5% of people from Europe and the Middle East (the balance having 5 or 6 copies). Because the markers location on the Y-Chromosome is not determinable, they are sorted from smallest to largest (385a/b is treated the same way), therefore it is possible to overstate or understate the actual genetic distance when making a comparison by eye.

Markers 464a-d are copies found at different locations on the Y chromosome. Results are always reported from low to high, when reading from left to right in loci 464 a - d. When a mismatch occurs, it must be taken into consideration whether the number of apparent mismatches are a result of the order of presentation of the Markers. The order of the results for these Markers may make it appear as if there are more mismatches or mutations than are actually present.

In Michael (Eng)'s case this means that his 3 loci differences and 5 mutation differences off the T2 Group baseline is reduced to a 2 mutation event difference and is shown as such with an mutation event difference of 23 / 25 so Michael (Eng) remains part of the T2 Group. In Gus' case his 5 loci difference and 5 mutation difference is reduced to a 4 mutation event difference with a score of 21 / 25 off the T3 Group baseline which means Gus forms his own individual DNA group called T3b. Michael-MH & Ed (NJ) has a 4 loci difference and a 5 mutation difference which translated to a 5 mutation event difference from the T3 Group, hence Michael-MH & Ed (NJ) also have their own individual DNA group called the T3c Group. As stated earlier, Gene with a score of 22 / 25 is still considered in the T Group due to the fact that his 3 mutations are all in one locus and is considered to be radical as it is 3 mutations off all others testers in DYS 393. Chris McTurnan has a total of 5 mutations but only a 4 event mutations off the T Group baseline.

The Y chromosome mutation rate PER DYS LOCUS MARKER is random, mutating once every 500 generations in each locus. This is an average as a mutation could and does occur in each locus at any time with you or with one of your ancestors that lived up to 500 generations ago. A generation is about 25 to 30 years more or less. The Mormons who are experts in this field state that a generation is 30 years long. In one of my German family lines that goes back to 1580, the average generation span is 29.6 years. See http://mctiernan.com/dnarules.htm for a look on fast mutations for the MacTighernans.

This web site http://www.wfu.edu/alb atross/gcircle/calcfull.html [there is an underscore between alb_atross] will enable you to type in your lat and long and then another MacTighernan's lat and long and see what the distance is between the two townlands in the above grid in nautical miles as the crow flies. As an example in the T3 Group baseline, Leo's and Eoghan's townland of Ummeyroe in Co Sligo is only 6.65 nautical miles from Jim (NJ)'s and Brian's townland of Tullycorka in Co Leitrim and only 2.65 nautical miles from Jim (MA)'s townland of Tap in Co Sligo.

On my maternal side I descend from Tara, rather a subclade of the T group which is T4. This T Group has nothing to do with our T Group in the MacTighernan DNA test. Tara was one of the 7 European daughters of Eve

Even though I am a male McTiernan, my mother was a Fries and her mother was a Blaies and her mother was a Bender so I have their mtDNA but my children would not. The mtDNA is passed down maternally not paternally so my children would have their mother's mtDNA not mine. This maternal mtDNA tracking is better explained at http://mctiernan.com/mtdna.htm
