If you are possibly interested in DNA testing or ancient genealogy / anthropology check out the BBC show the Blood of Vikings. This is the same title as the BBC series from a couple of years ago, and it may be a first-time showing in the US. It's scheduled for 6:00pm Eastern, 3:00pm Pacific on the Discovery Channel's Science Channel. If you've never visited the BBC website for this program, it's worth a look: http://www.bbc.co.uk/history/programmes/bloodofthevikings/
