Something very cool for all the family history buffs out there. Dynastree allows you to more sense of your lineage, by tracing the roots of your surname. They have a new surname mapping feature that allows you to see the geographical dispersion of your last name across the country. Check out your surname map. Adams is #30 on the list of most frequent surname in the U.S. and there are folks with the name in all 50 states (Texas has the most). Very cool.
Thanks Mashable
