If you're into genetic genealogy - and I mean seriously into it -- you'll definitely want to read Journal of Genetic Genealogy. It's online, free and edited by some of the best minds in the biz, including my Trace Your Roots with DNA co-author, Ann Turner, M.D. (in case you haven't guessed it, she's the smart one!). They're aiming for quarterly, but so far, it seems more like twice a year -- but that's probably a good thing because they have the kind of articles that you'll want to ponder for a while. Looking forward to the next issue (Fall 2006), which I'm assuming will come out shortly.
