The MacTighernan DNA Test

McTernan / McTiernan / MacTiernan

The goal is to map all MacTighernans both geneticly and geographicly. With 53 tests completed, 1 in process and 3 TBR, the DNA sampling in this test is random currently from 53 MacTighernans or surname variants from around the world that at the time of testing live in nine countries on 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.

To date, almost all 53 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, 35 out of 53 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 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), Cathal, Scott (CO), Sean-SF and possibly 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 is at 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 53 MacTighernans fall into 12 separate 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.

How many MacTighernans are there ?
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

This info can be confusing so please read the headers and footers in the following grids to make it easier to understand

The 12 separate and different MacTighernan DNA groups are labeled with the letter T. It 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, Rory's from 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 Mountallen Townland in Co Roscommon and has the date 1671 etched in the fire place mantle which implies the year of construction of their family home. John C. McTernan [T3a], the well known Co Sligo arthur once told me that when he was the Chief Librarian of Co Sligo, he remembered seeing historical legal documents that led him to believe that the Mount Allen / Heapstown McTernan family was related 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 for some time being the exception.

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 none of our 12 DNA groups match any other DNA groups in this MacTighernan study.

Those in the baselines for each of the 12 separate MacTighernan DNA groups are a perfect 25 / 25 genetic match to each other in their group

Above numbers for perfect match of 25 / 25 are in red background - for the specific DNA groups

A 22 / 25 match or less in the above 2 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.

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. In the below grid, Joe's family of Naas, Co Kildare is related to Sean-sol. 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.

DNA kit numbers in above chart are in Italic, other numbers are YOB. Perfect 25 / 25 matches are in red and are the baseline for the T DNA group

All townlands above are in Co Leitrim unless otherwise noted. Last row is tester's location at the time of the test
Ancestors in the light colored row in the above grid were born c. 1800. ** = 3 mutations in one locus * = immigrant

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.

The McTernan family history from Tullycorka written by Brother Gerald McTernan shows that he is related to Jim (NJ). Leo, Eoghan, Jim (MA), Jim (NJ), John W., Cathal and Scott (CO) match 25 / 25 with the conclusion that these Leitrim and Sligo McTiernan families are connected. John L., Cindi, Maryellen and Kathy are related to Scott (CO). 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. Mary, the sister of Cathal's Great Grandfather James married Michael MacTiernan, "The Bull" from Clenaghoo. James 1876-, had four additional siblings, Patrick, Bridget, Ellen & Mary Gaffney, nee McTiernan

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 townland of origin for Rory [kit 1029] in Kilronan parish in Co Roscommon. Rory's Mountallen.

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. Almost all of the MacTighernans originate in the area covered by N 54.19.50 to N 53.48.35 degrees to W 8.43.48 to W 7.06.20 degrees.

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 twelve unrelated, separate and distinct DNA groups. 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 12 DNA group.

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 12 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, Chris will begin the ninth DNA Group called Tc.

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 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, T3b & T3c 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 seven of the twelve 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 profil of all MacTighernans specifically from their origins to the country they live in presently. If you are a close genetic match with another MacTighernan in your DNA group you may have a lot of work to do to find a common ancestor but still you are on the right path. Also, the remaining mystery 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 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 twelve different genetic groups from one small area of Connacht, Ireland all with the same surname.
