Supposedly my mom's family members are direct descendents of Jesse James.  Explains a lot about my grandmother. 
 
My parents are "mutts" German, Irish, Scottish, French, English...heaven only knows what else.
My birth mother's last name is pure Irish....but I really don't look Irish at all.......
Personally, I think it would be cool to be a descendent of Jesus, like in the movie 
Dogma, or in 
The DaVinci Code.
