Given Co. Mayo's history, I can't see how any meaningful conclusions can be drawn without examining the surnames of those tested. Mayo saw significant immigration from Ulster over the years followed by significant post-famine emigration. The population of the county in 1971 was 28 percent of the 1841 population, more than a 70 percent drop!

Let alone the fact that it's home to surnames with origins in Uí Fhiachrach and Uí Bhriúin, both of which appear to be M222 dominated (the semi-mythical half brothers of Niall) -Paul (DF41+) On Mon, Nov 11, 2013 at 11:31 AM, Rob McFadden <[email protected]>wrote: > Given Co.

Using DNA sampling, geographically measuring frequency, distribution and diversity (today), measures current frequency, diversity and distribution today. These measured (today) in their geographical locations does not equate with what these numbers would have been 100--200--300 years ago let alone 2000 years ago. To use an obvious example, New York City has probably the largest most diversified populations in western culture. How did this diversity occur? Through migration and mixing of populations. Because of its large population as well as large ethnic populations there will also be large frequency of both ethnicity and Ydna associated with those ethnic cultures. Does that mean that NY city is a city of origin for any of it? No it does not. Now this is a rather obvious example, but it is pertinent. Of the populations of Ireland (and the Isles general, really) are None technically indigenous...they all migrated in, out, back, and within at different times over the last couple of thousand years or so. Ireland to the greater extent is a great melting pot of Western Europe and the end of the road so to speak. We should find a high distribution, diversity and frequency of R1b sub-clades there, and R-M222 (most probably mutating in a man in the Isles among populations associated with western Europe and westward migration) understandably would be found with high distribution, frequency and diversity particularly if one considers the migration history within the Isles themselves. Confusing today's frequency, distribution and diversity with origin is a ever common theme within the GG community. I really do hope that we avoid these arguments as they are pointless and so divisive. I intend to focus on which groups SNP out the same and try to understand them better and stay away from the ever evolving theories of origin. Using the often assessed ancestral origin claims is even a better gauge than today's measures of frequency, distribution, and diversity, and we all know how accurate/and/or the reverse thereof these claims are coupled with the surname difficulties.
