The MacTighernan DNA Test

McTernan / McTiernan / MacTiernan

The goal is to map all MacTighernans both geneticly and geographicly. With 73 tests completed and 4 TBR & 1 TBD, the DNA sampling in this test is random currently from 73 MacTighernans or surname variants from around the world that at the time of testing live in ten countries and five continents with no correlation except the same surname and the same close proximity of origin in Cos Leitrim, Sligo, Roscommon and Cavan. 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 73 tested MacTighernans that know their origins come from this small area in NW Ireland shown in green on the map on the left, 450 square miles more or less with the three exceptions, Gus and Michael (NJ) 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 area of Ireland. Based on the DNA study at this point in time it appears that the origins of most MacTighernans, 48 out of 73 are in Co Leitrim. The Google earth satellite image that marks the townland origin of each MacTighernan if known is at this 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 monastery and beheaded the guardian and several of the friars. 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 Ed (NJ), Scott (CO), Cathal, Sean-SF, Jim III and Charles whose family origins are in South Leitrim.

Philip O'Rorke, The O'Ruairc of Bréifne whose family were the past kings of Drumahaire in Co Leitrim has taken this DNA test. The O'Rorke DNA web site  http://www.familytreedna.com/public/roark/. Desmond O'Conor, The O'Conor Don, whose ancestors were the past high kings of all of Ireland has not yet agreed to take the DNA test. With the tests completed so far we 73 MacTighernans fall into 14 separate, distinct and unrelated DNA 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 to 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. The Genographic project sponsored by Nationalgeographic and IBM goes into this in great detail https://www3.nationalgeographic.com/genographic/index.html Use my kit number to see the display, FWRFL845CH

There is no way to know for certain what the total number is for distinct genetically separate MacTighernans on a worldwide basis. At this time it would be a guess to say how many of us there would be worldwide. The below chart gives a reasonable approximation as to the individual MacTighernan density in Ireland and the main 4 countries of immigration as of 2004.

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


How many MacTighernans are there now ?
As of 2004 the approximate total of individuals by country with surname spellings of McTiernan, MacTiernan, McTernan. It is safe to say that
the real total of separate MacTighernan families is less than these numbers These numbers exclude the DNA tester and their related family members if known

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 Sligo and Co Leitrim. The historical family origins of the majority of the 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 start at around the 1850s going no further back in time.

The McTernans of Co Fermanagh may have disappeared and there are no known descendants of the other two 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.

Acording 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 Sweetwood townland in Co Leitrim.

A recumbent tombstone in Killargue old cemetery 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 illistrated 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. Above the shield and helmut 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 make it easier to understand

The 14 separate, distinct and different MacTighernan DNA groups are labeled 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 in Co Leitrim & 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, 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 to Heapstown, Co Sligo.  John C. McTernan [T3a], 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, Co Leitrim and relate to the Leonagh, Sheskin and Rockfield McTernan families. 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.

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 result is that if you are in one group you do not genetically relate to anyone in any other DNA group.

Those in the baselines for each of the 14 separate MacTighernan DNA groups are a perfect 25 / 25 genetic match to each other in their group

The Great MacTighernan Mysteries

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 was a member of the Societe Generale in Paris, France for which he received an annual sum of money. Reverend Stephen's personal papers were uncovered in 1907, by Rev. Charles Comey, curate of Cloonclare, Manorhamilton. The papers were found 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 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.  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 the 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.  In historical documents the Rockfield McTernans and the Heapstown McTernans [ Rory's line in the T group baseline ] are called kinsmen and are related via the maternal line with the paternal link still unknown.

4. Solved: the pamphlet written in 1845 by James MacTernan, <1815--1855, of the Mount Allen 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.

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

6. The McTernan School: located 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.  Charles' son Donald married and lived in France having two daughters.  Male line may descend from Charles' uncle, Patrick, 1863--,  who was born in Boston. This family immigrated to the Boston area from Co Leitrim. Long shot for DNA match.

7. Solved: The McTernan Street in Cambridge, MA, USA formerly Lake St. right outside of County Boston.  This is Myles McTernan's family in the Te DNA Group

8. Solved: 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) is a descendent in the Ta DNA Group

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

10. Origin of McTiernan Close, Wilsonton, QLD, Australia 4350: is probably named after Sir Edward McTiernan who is related to Leo McTiernan in the T3 Group baseline.

11. Lac McTiernan, a lake in Quebec, Canada, a 7 hour drive  north of Ottowa 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 1930’s. To find out more about this man and his father, David McTiernan, who both worked in the backcountry of Gatineau River, you should 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 Pontiac, 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.  This family is in the T Group.

12. Do we genetically relate to The O'Conor Don, whose family were the past kings of Ireland as stated in the Annals of the 4 Masters.

13. What might be our connection to Rathmacternane, a townland in Killoran parish, Co Sligo listed in the Hearth roll of 1665 with a person named Cahill McTanist? listed as living there. 

14. Whereabouts of the McTernan Stone, an excessively heavy mill stone lifted and carried to the front of the Abbey Manor Hotel in Drumahaire by Thomas McTernan, the grandfather of John-Rev in the T Group baseline.  The stone thereafter was known as the McTernan Stone. 

15. 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 any connection to any in the DNA test.

16. Private Patrick McTiernan, service number 3755 in the 34th Foot (Cumberland Regiment) was wounded in the final attack on the Redan in the Crimean War and also served in the Indian Mutiny of 1857. Awarded the Indian Mutiny Medal: The Indian Mutiny Medal was a campaign medal approved in 1858, for issue to officers and men of British and Indian units who served in operations in suppression of the Indian Mutiny.To what family does he belong ?

17. Private John McTiernan, in the 88th Foot (1st Cannaught Rangers)  fought in the Indian Mutiny of 1857 in the battle of Central India and awarded the Indian Mutiny Medal.  Central India battle: January - June 1858. Awarded to all those who served under Major-General Sir Hugh Rose in actions against Jhansi, Kalpi, and Gwalior. Also awarded to those who served with Major-General Roberts in the Rajputana Field Force and Major-General Whitlock of the Madras Column, between January and June 1858. To what family does he belong ?

18. A horse by the name of MacTiernan is racing in Dublin for the 2010 & 2011 season.  He is running well, owned by Christine Kiernan.  Why did she name the horse MacTiernan ?

If anyone has any information on any of the remaining mysteries above please let me know

DNA Scoring

Each DNA Group is of equal standing. Each group's baseline is where all in that group started.  The baselines of the 14 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 are in that group just not in the baseline.

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.

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, and therefore more time between you and the other MacTighernan.

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.

Above numbers for perfect match of 25 / 25 are in red background - for the specific DNA groups, the red + sign means the grouped individuals are related

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. 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 still part of the T Group.

73 tests completed in the MacTighernan DNA test as of May 5, 2012

Mark most likely relates to Martin from Dublin as both 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. 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.

Mark 673's & Martin 3713's townland of Leonagh, Co Leitrim is now in the Catholic sub parish of Creevelea as listed in the above chart. Back in time [c 1857 or before] Leonagh was in the Catholic Parish of Killargue. Leonagh lies on the shore of Belhavel Lake at the upper end of Killargue parish and is today a sub parish of Drumkeerin. [6-7-2001 letter from Padraic Cullen]. Mountallen, the original family seat for Rory's family [kit 1029] is in Kilronan parish in Co Roscommon.

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 14  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 14 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.

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 23 / 25 which means that he and Douglas genetically relate. Douglas 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 at least until more is understood.

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, Tc, 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

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 eight of the 14  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 and in fact are 4th cousins one generation removed.

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 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 14  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 14 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 14 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. The last in the O'Rorke line, Philip O'Rorke (kit 2099) is The O'Ruairc of Bréifne. So far, Philip's test scores are beyond the threshold of genetically relating to any of the 14 MacTighernan DNA groups. In the future there may be a MacTighernan that is a match with Philip. I have asked Desmond O'Conor who is The O'Conor Don to also take this test. The O'Conors of Roscommon match 21 / 25 with the T3 Group. The O'Conor family has started its own DNA test that is found at http://www.worldfamilies.net/surnames/c/conner/results.html

This web site gives a brief summery of the DNA rules of the road and also goes over how an individual that is not a MacTighernan might have a close 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 we are all on the same branch. All 14  separate MacTighernan DNA Groups, and Philip O'Rorke fall into the larger DNA group called the Haplogroup R1b1 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 R1b lineage is also the haplogroup containing the Atlantic modal haplotype.

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 your 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 14 DNA Group baselines. A match of 23 / 25 or better with one of the 14  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. 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 Ed (NJ) also has his 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.

A reference web site to the area of Breifne, http://www.breifne.ie

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 terms of 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.

The MLE (Most Likely Estimate of WHEN that common ancestor lived is the real question. This web site http://nitro.biosci.arizona.edu/ftdna/TMRCA.html does a very good job of explaining the distance in generations to a common ancestor based on the mutation event frequencies

The Byrne/Bryne/Burns family is also doing a DNA test, administered by Terry Barton: http://www.worldfamilies.net/surnames/b/byrne/

The Carney family also has a DNA web site at Carney/Kearney DNA project, organized by Dr. Christopher Cairney: http://www.worldfamilies.net/surnames/c/carney/index.html

Eoghan McTiernan's extensive family web site is at http://www.e.mctiernan.btinternet.co.uk/Welcome.html

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

The DNA scores of famous historical people: http://www.isogg.org/famousdna.htm

If you are a male McTernan / McTiernan / MacTiernan and you want to participate in this DNA study please let me know. We have a special family group rate at http://www.familytreedna.com of $124 US for the 25 marker test. If you happen to own a couple of banks and several residences then I hope you might pay the cost.  If you don't then I will pay the cost as it is my only hobby. I have written to The O'Conor Don to see if he would do the DNA test which might once and for all prove if the MacTighernans descend from the O'Conors as stated in Irish history some 900 years ago.

Note: Kirsten McTernan in Wales has a tremendous web site that shows an outstanding talent for new photography and design: www.kirstenmcternan.co.uk

Might we all end up 'Hiberniores Hibernis ipsis' (more Irish than the Irish themselves).
