John, there is another McDowall in Ysearch who claims to be descended from

Fergus de Galloway.

His number is QF7W2


That's interesting, Alan. I did a quick look in Ysearch and he matches
two other McDowalls, the McCampbell samples and a couple of Cowans, among
others. The McCampbell is the one recently discussed from Galloway.

The one Bernard mentioned as NAZGR who is a close match to your sample.


I think however if you're going to try and establish that this McDowell
family (and perhaps the Kennedys) were descended from Fergus of Galloway then
you need more samples than this.

Fergus of Galloway died in 1161 AD. (according to Wikipedia). Some may
disagree but I think you'd need more than just the M222 haplogroup to
determine that he was the common ancestor of both (and perhaps of more Galloway
families). I think you'd need a very close connection in DNA as well,
perhaps even a recognizable DNA pattern.

I base this on what we found among Cavanaghs, kinsellas and O'Byrnes in
the Leinster modal project. They all share a readily distinguishable modal
similar in some ways to M222 but less strong. Further the Cavanaghs and
Kinsellas, who both descend from a Dermot MacMurrough, the King of Leinster c.
1200 AD. still share some unique markers, at least based on the samples we
have (only two Kinsellas).

If you ask Sandy though he will tell you (as he told me) that according to
his simulation software these shared markers should have mutated away from
anyone descending from a common ancestor ca. 1200 AD. So there might be
some argument on how closely their DNA must match to establish a shared
descent.

I don't think M222 in Galloway needs to be explained by a descent from
Fergus of Galloway but it would be interesting if it could be established.
You'd have another Nial or Ghenghis Khan figure to talk about.
