Did SNP R-M222 Spread from County Mayo?

Spencer Wells, Director of the Genographic Project (GENO 2.0) sponsored by National Geographic, is scheduled to travel to County Mayo this weekend to announce that it appears SNP R-M222 may have originated there. This gene is associated with Scots Irish descent. Dr.Wells is also expected to identify more that 20 more recent SNPs that branch the gene flows below R-M222. These findings should be of great assistance to Scots Irish researchers by helping them narrow the focus in their search for their ancestral homelands.
