Democrats can't unite the increasingly bitter race between Barack Obama and Hillary Clinton, but genealogists can. It seems he's distantly related to Brad Pitt and she's a far off cousin of Angelina Jolie.

Researchers at the New England Historic Genealogical Society are reporting many famous branches in the candidates' family trees.

Clinton has familial ties to Madonna, Celine Dion and Alanis Morissette. Obama can call six U.S. presidents, including George W. Bush, his cousins. McCain is a sixth cousin of first lady Laura Bush.

Other Obama cousins include Vice President Dick Cheney, British Prime Minister Sir Winston Churchill and Civil War General Robert E. Lee.
