Any Kinsellas, Murphys, Cavanaghs, McEvoys or other Leinster people out there interested in DNA research?
We think we've identified a DNA cluster in Leinster linked to the ancient chieftains of the Lagin in Ireland. So far it appears in O'Byrnes and Cavanaghs, two of the leading chieftains of Leinster (plus possibly a couple of O'Tooles).
We've been calling the DNA signature the Leinster modal. It can be found on Ysearch, the public DNA database maintained by FamilyTree DNA (B9NW4). This modal was developed by the head of the Byrne DNA project at FTDNA. We would be very interested in seeing if other Leinster families also matched the DNA.
You can read about it here.http://members.aol.com/Lochlan4/leinster.htm
Some common Leinster surnames include O'Byrne, Kinsella, Cavanagh, Murphy, O'Toole, McEvoy, Dowling, Whelan or Phelen, O Dea, O Dee, O'Connor Faly, O Dempsey, MacColgan,
O'Houlihan & O'Hennessy, O'Dunn, O Dooley, O Farrell,
MacCrohan, O'Ryan, O'Gleeson, O'Donegan,
O Mulligan or O Milliken. There are probably many more than this but these are named in pedigree collections or the Topographical Poems.
If you've already have a DNA test and your family is from Leinster we'd like to hear from you.
The basic 12 marker DNA modal is:
In the Trinity database, better known for it's Nial study, the DNA is found almost exclusively in the south of Ireland, heaviest in Leinster but present in significant amounts in Munster. It's strongest concentration is in surnames from Leinster, reaching levels of 61% in Byrnes from Leinster. These levels are typical of the Trinity DNA study, which found most Irish surnames show evidence of multiple founders or male introgression.
There are also matches to the DNA in the lowlands of Scotland (a large group of Beattys) and in England. If O'Rahilly (Early Irish History and Mythology) is correct the Lagin DNA originated in SW England and came to Ireland in the centuries prior to the Roman invasion of the British Isles.
This DNA study is in its infancy. We need more DNA samples from Leinster surnames that match the O'Byrnes and Cavanaghs. If interested you can respond to me off list at Lochlan@aol.com
