MacAuley/McCauley Clans of Ireland
SEE LATEST RESULTS ANALYSIS
In 2003 the MacAulay Clan Society voted to undertake a DNA study using FTDNA as the research laboratory. As of December 2013, 144 men named MacAulay, McCauley, etc. had joined the DNA study.
JOIN THE DNA STUDY!
The study is open to both Scottish and Irish MacAulays, including all the spelling variations of the name. Participants need not be members of the Clan Society. DNA samples must be from males named MacAulay (any spelling variation) since the test is for Y-chromosome data. Female MacAuleys can participate by recruiting their brothers, fathers, or cousins to donate DNA. The sample is obtained by a painless cotton swab inside the mouth.
The MacAulay Clan Society decided to use FTDNA Laboratories for Y-DNA testing . It is crucial that all participants use the same testing company because the variuos labs use different measurement protocols, and results from one company to another may not be directly comparable. The rates for the two most relevant tests are:
Y-DNA-12 marker test
TO JOIN THE MACAULAY DNA STUDY, USE THIS FORM FROM FTDNA LABORATORIES:
For most MacAulays
the 37-marker test will provide enough data to identify which of the ancestral
MacAulay clans he is descended from, and often the 12-marker test will
be sufficient. Since FTDNA Labs will save your DNA sample, an upgrade
can be ordered pretty easily. The cost of upgrading from 12 markers to
37 is $99. People who are cautious about this new field can get a 12-marker
test first, and after reviewing the results s/he can decide whether to
buy an upgrade.
********MacAulay DNA Results *******
So far 36 MacAulays have signed up for the Clan MacAulay DNA study. In addition, a private study DNA study of MacAulays from North Uist has 13 participants, and they are collaborating with us. Additionally, five McCulleys have formed a separate study and are making their data available. In all, we have DNA data from 54 MacAulay men available for analysis.
Our analysis so far has identified nine DNA groups which include all but 8 of the 54 MacAulays. Three of these nine DNA groups have been matched with ancient MacAulay clans or septs: (1) the MacAuleys of Fermanagh (IG type 1), (2) the MacAulays of North Uist (SG3), and (3) the Macaulays of Lewis (SG4 and SG5). One of the DNA groups is not a Celtic clan at all, but a group of French Hugonaut immigrants who changed their name to McCulley and McCauley (SA1). The other four groups have not yet been definitively matched to an ancient clan, but a lot has been learned from the DNA, and I am optimistic that we will soon match these groups as well.
Of the eight MacAulay DNA participants that have not yet been matched to a DNA group, there are several possible explanations. Four of them probably fit in one of these DNA groups but we will need more tests or genealogical information to confirm. Another obvious explanation is that so far they may be the only member of their clan to take the DNA test. Alternatively, there could have been a "non-paternal event" in their direct male lineage, such as adoption. Finally, one of these eight DNA participants is named "McElyea" and it could be that this is not a variant of McAuley.
The nine DNA group-patterns that have been discovered so far are shown in detail in the Data Table at the end of this article. They are:
Gaelic type 1 (D.J. Macaulay,
M.P. McCally, D.J. McCauley, W.S McCauley, Dale McCauley)
ScottishGaelic Type 5 (Hugh MacAulay)
Scottish Alannic (G-Haplogroup) (A.J. McCulley, Steve McCauley,
and R. McCully)
It is very likely that the men within each group are closely related to each other, but unlikey that they are closely related to the men in the other groups. (For example, the FTDNA Time Predictor estimates that it is 89% probable that D.S. McColly and E.R. McCauley [who are both SG type 2] had a common male ancestor 500 years ago; but the likelihood that D.J. Macaulay [SG type 1] and E.R. McCauley [SG type 2] had a common male ancestor 500 years ago is less than 1 percent.) We know that there were at least five MacAulay clans/septs in Scotland and at least two in Ireland, so these DNA results seem to be sorting out along clan lines as expected.
Gaelic type 1, (Niall of the 9 Hostages)****
*****Scottish Gaelic type 2*****
Six participants have this DNA pattern, and they seem to all be of Scottish or Scotch-Irish ancestry. Despite the large number of McCauleys in this group, we have not yet been able to link it to a specific clan territory in Scotland. D.S. McColly, E.R. McCauley, and W.B. McColly had identical 12-marker DNA results. D.S. and E.R. had 4 differences at the 37-marker level. W.B. McColly has information on an immigrant to America born in 1754 who is a common ancestor with D.S. McColly. W.B. is sure his ancestor immigrated directly from Scotland, while E.R. has not ruled out Scotch-Irish immigration. The FTDNA Time Predictor estimates that it is 89% probable that D.S. McColly and E.R. McCauley had a common male ancestor 500 years ago.
Gaelic type 3, (North Uist)****
Gaelic type 4, (Isle of Lewis)*****
*****Scottish Gaelic type 5, (Isle of Lewis)*****
Hugh MacAulay traces his ancestry to the MacAulays of Uig Parish in the Isle of Lewis. This is the clan to which the famous Lord Macaulay (Thomas Babington Macaulay) belonged. Although we only have one member from this group, I have shown this pattern in the chart in the Appendix, because of the great interest in this clan. (Note that it is very similar to Scottish Gaelic type 4, and the difference might be due to two recent mutations.)
Alannic (Haplogroup G2, (Hugonaut)****
Gaelic type 1, (Fermanagh Maguire)****
Gaelic type 2, (Fermanagh)****
***Irish Gaelic type 3, (Daldriadic)**** DNA researchers have identified this DNA pattern as the Daldriadic baseline DNA signature. This DNA pattern is found in the chiefly families of many clans of Scotland and Ireland, mostly in Ulster, Western Scotland, and the islands. It is the most common pattern in the McDonald Clan, although not among the direct descendants of Somerled McDonald. All three McAuleys in this study trace their ancestry to County Antrim. Sean suspects that his family is ultimately related to the Scottish clan of Ardencaple.
***Irish Gaelic type 4, (Three Collas)**** DNA researchers have identified this pattern as the most likely Y-DNA of the three Collas, who were semi-legendary brothers that conquered much of northern Ireland in the 4th Century A.D. One of the Collas, Colla Uais, became High King of Ireland in 325. Numerous families of Ulster and Scotland claimed Colla ancestry. Two of the testers with this DNA pattern have ancestors from Londonderry.
