If you mean Duncan I'm puzzled as this seems to be from the NE as a surname (irrespective of its origins as a first name). Can you point me to this data? You would have to compare the same group size for the comparison you cited of course. Otherwise the groups are so disparate in size I would almost draw the opposite conclusion.
I haven't crunched any TMRCA numbers for my Kennedy data which is offline, although I would mention that our group modal exactly lies on the main M222 modal. Based on recent posts, this may not mean anything at all in itself.
