Otherwise known as the "Where yer people hailed from" test. My brother is into genealogy, and figuring out our lineage. It never interested me all that much, even when his detective work indicated that our father's unknown original parents (he was an orphan, left on a doorstep in Philadelphia during the big flu epidemic in the 1920s) were probably from the Ukraine, and Jewish.
More interesting to me was his latest endeavor, in which he submitted DNA samples to a company and got a "readout" on where his DNA (and presumably mine as well, since our Mom was SO not a person given to fool around) *came from* on the planet. The company says that it matches the samples against many thousands of similar samples tied primarily to geographical locations around the world, and then they ship you a report on what they found. I have no idea if it's legit. I just looked as his (and presumably my) results, and they sounded "right" to me: 99% European (broken down) 54% English 28% Irish 12% Eastern Europe 05% Western Europe Cheap entertainment...what can I say? Just posted in case anyone here gets all Woo Woo behind the idea of figuring out where *their* DNA comes from. The site is dna.ancestry.com. Not responsible.
