Please note that the announcement below applies equally to the equivalent mutation rates on 67 and 111 markers.
CLAN GREGOR ACCEPTS MEMBERS ON THE BASIS OF A DNA SIGNATURE PRESS RELEASE as reported in all the Scottish newspapers, The Times, various weeklies and local radios: THE CLAN GREGOR SOCIETY OF SCOTLAND Comunn Chloinn Ghriogair Founded 1822 – Charity No. SCO 07391 Patron: Sir Malcolm MacGregor of MacGregor Bart
Press release for immediate publication June 10th 2007
At the Council meeting held on Friday June 8th 2007, the Clan Gregor Society of Scotland agreed that it will, from this point onwards, accept into full membership of the Society individuals with ANY surname who can show, through DNA testing, that they have a DNA signature which matches, at the accepted degrees of mutational difference, that of the main MacGregor DNA signature. Council has taken this decision in recognition of the fact that, as a result of Clan Gregor’s past turbulent history, individuals were required to assume names which were totally divorced from their actual clan name, and although such name changes were often documented at the time, others were not. The Clan Gregor Society Council recognises that the ancestors of some MacGregors chose not to return to the original clan name for a variety of reasons, and that advances in DNA testing now allows the descendants of such individuals to be identified as belonging to the clan.
In taking this decision the Council is conscious that it is the first Clan Society to promote membership on the basis of a DNA signature and it is to be hoped that other clans will follow this lead. Details: The Clan Gregor Society will admit to full membership of the Society anyone who can show 23 markers out of 25, or, up to 31 (but normally 33) markers out of 37 in common with the main MacGregor DNA profile which is found as kit number 2124 on the Family Tree DNA public website for the Clan Gregor Project (), and additionally, where marker DYS385a normally equals 10 (ten). We take this as the modal signature. For mutations this equates to a genetic distance of up to 6 (six) on 37 markers.
The Clan Gregor Society also recognises that there is a separate Irish based DNA profile for M(a)cGregors which is distinct from the main M(a)cGregor profile, indicating a probable separate origin for the name. Council will therefore also admit to full membership on the basis of this DNA signature, again without relation to surname. The same broad restrictions apply as in the previous paragraph except that for this group the reference kit will be 4715 but with the following alterations: marker DYS464b will be considered as having a modal value of 16 and DYS460 to have a modal value of 11, and DYS 19 (394) a modal value of 14. For the moment the scores on CDY a and b will be discounted in determining the Irish signature and therefore the match which will be considered is up to 30 out of 35 (that is, a maximum genetic distance of 5). We believe that DNA testing now provides an extremely reliable tool for confirming surname-based descent based on analysis of the Y chromosome.

10th June 2007 [older news] MAPPING OF MOST DISTANT KNOWN ANCESTOR I have finished updated the mapping of earliest ancestors, where known. Where there is no information please DO enter your own data and change any information which has now been superceded by new material. Anyone wanting to put in a country of origin for an MtDNA result is invited to do so. I suggest that where the place is not known (e.g. where in Ireland) that the longitude/latitiude is set somewhere central in the country and the information bubble suggests the country but indicates somehow that the place is unknown. It had always been assumed that because the clan was so persecuted only ‘true’ MacGregors would bear the name. Peter Lawrie’s (Vice Chairman of the Clan Gregor Society) recent work has demonstrated just how many of the bloodline MacGregors were in fact killed during the troubles which came upon the clan in the 17th century. Nevertheless, it is clear from the DNA that Clan Gregor does indeed have its origin in one individual but also that it contains ‘part-takers’ sharing a common ‘Celtic’, probably Dalriadic culture, AS WELL AS ‘part-takers’ whose paternal ancestry is Icelandic or Viking but whose ancestors over 400 years became entwined with the MacGregors. We should not be surprised to learn of the Scandinavian/Danish/ Norwegian connection since the Viking raiders were well known for their activities along the West coast of Scotland.
