After watching Who Do You Think You Are? and Henry Louis Gates Jr.'s Finding Your Roots series, I thought it might be fun to have my DNA analyzed for ethnic background. I wasn't expecting much, and that's what I got, but I'm dying to have my SO's done, as I suspect Jewish Converso on one or both sides of his family. A lot of Spanish Jews fled to the New World with the Inquisition hot on their heels and then had to go underground once they arrived. There are lots of "crypto-Jews" among Mexican-Americans living in New Mexico who are just now discovering their heritage. http://www.theatlantic.com/past/docs...0/12/ferry.htm
I will say I was puzzled to find myself more Scandinavianthan Western European and with nary a sign of the UK strain my family tree clearly shows. Perhaps as more people are tested, that will fill in the 5% "unknown." Or perhaps "unknown" is my Neanderthal strain...
