I recently had Y- DNA testing for genealogical purposes. The results were quite unexpected. I do not yet have all of the results back yet but I have enough to say without a doubt that I have no blood relationship to the Scottish clan whose name I carry. I am not even on the same branch of the evolutionary tree, (Haplogroup)
http://en.wikipedia.org/wiki/Haplogroup. The DNA results put me in a recently identified clade of haplogroup I1b1 (I1b1 Isles A) that is considered to be indigenous to the British Isles. It is a small group and thought to be very old. My ancestors may have been among the first settlers in the British Isles following the last glacial maximum, 8,000 to 12,000 years ago.
These clades branched off I1b1 – Dinaric, and separated before the last glacial maximum ended. The descendants of I1b1 – Dinaric are heavily represented today in the Balkans especially Croatia and Bosnia.
Haplogroup I is a branch of haplogroup F*. According to current theories, Haplogroup I first arrived in Europe around 20,000-25,000 years ago from the Middle East. It is believed to be associated with the Gravettian culture.
http://en.wikipedia.org/wiki/GravettianCurrently four subclades of I1b1-Isles have been identified.
A. Irish/ Scot
B. English / Irish
C. Irish
D. Irish
It will be interesting to see how this all plays out.
I plan to have my MT-DNA analyzed next year.
