Is this your work? It is really wonderful. I've just seen this post and will read up on the Blog later when I have time. Interesting that M222 might have been a Hallstatt marker. I not so sure about that? I know Jean Manco was pro that theory or the possibility of it.

Not necessarily a Hallstatt or La-Téne marker per se (whom I suspect were all R1b-U152<L2) but it is more frequent in ulstermen which is interesting. The most basal snps are found in Britain so I think Jean (who I spoke with a few times before her passing) was onto something there as the Y phylogeograpic landscape did change in Ireland around that time due to a shrinking population and local founder effects leading to the the M222 snp becoming most prevalent with O’Neill clan’s ascendency. And yes to answer your first question.

M222 is nearly just as high in Connacht which is where my father is from and he was also M222. The Ui Neill and Connachta (who were kin) were prevalent in Ulster and Connacht so that most likely explains the prevalence of M222 in those areas.

Jean was a lovely lady. I was so sad when she passed as she was so knowledgeable and very gracious in her approach. I'll keep an eye on your blog as it is great to have a dedicated Irish genetics blog especially by someone that has a good knowledge on the topic.
