Enormous thanks to Mark for putting his thoughts together in his two long posts on Genealogy DNA. Conscious of my weak point, I would like to just focus on the DNA. John MacEwan made the point that his "cluster 47" aka Scots aka Colla aka Dalriadic R1b, seems too old and British to be accounted for by any founder coming out of Ireland. If we accept that, it still might be true that with a long haplotype (lots of markers) we may identify a branch which does meet this description. However (I bet you can see where I am headed!) this is going to be a *big* problem if we just keep comparing "13 24 14 10" people, as such people make up perhaps nearly 20% of all Scots. With this I'd like to note that I now believe/hope I have representatives of the two main MacLea lines (Lismore and Achnacree) getting all non-FT DNA markers tested at DNA FP. I call on all clans with substantial membership in "cluster 47" to consider getting a few selected members to test as many markers as possible. There are theories to be tested, and the wonder of it is that the results are sure to surprise everyone in some way. Also please everyone try to find Irish interest. We ideally need much better comparisons to Irish R1b haplotypes. Highest Regards Andrew PS pardon the cross postings, but Scots DNA seem empty!
