So I put my DNA in to 23andMe before the FDA curtain came down. Here is my ancestry, computed through Dodecad software:
I guess that makes sense for an Irish boy. It turns out that I'm also Y chromosome haplotype R1b1b2a1a2f2, which lodges me firmly in the common Northern Irish gene pool. My mitochondrial haplotype is H, which links me (apparently) to Napoleon Bonaparte, Susan Sarandon, Luke the Evangelist, and about 50% of Europe. So I'm not terribly special. Which is not necessarily a bad thing!
