Barack Obama and Cousin Brad Pitt

Barack Obama likes to mention his distant cousin Dick Cheney in his stump speech.

Naturally, he uses it as a laugh line.

Now, Obama has more cousins to talk about on the campaign trail. That's a good thing since the Cheney black sheep joke is horribly stale.

BOSTON (AP) -- This could make for one odd family reunion: Barack Obama is a distant cousin of actor Brad Pitt, and Hillary Rodham Clinton is related to Pitt's girlfriend, Angelina Jolie.

Researchers at the New England Historic Genealogical Society found some remarkable family connections for the three presidential candidates—Democratic rivals Obama and Clinton, and Republican John McCain.

Clinton, who is of French-Canadian descent on her mother's side, is also a distant cousin of singers Madonna, Celine Dion and Alanis Morissette. Obama, the son of a white woman from Kansas and a black man from Kenya, can call six U.S. presidents, including George W. Bush, his cousins. McCain is a sixth cousin of first lady Laura Bush.

Genealogist Christopher Child said that while the candidates often focus on pointing out differences between them, their ancestry shows they are more alike than they think.

"It shows that lots of different people can be related, people you wouldn't necessarily expect," Child said.

Obama has a prolific presidential lineage that features Democrats and Republicans. His distant cousins include President George W. Bush and his father, George H.W. Bush, Gerald Ford, Lyndon Johnson, Harry S. Truman and James Madison. Other Obama cousins include Vice President Dick Cheney, British Prime Minister Sir Winston Churchill and Civil War General Robert E. Lee.

"His kinships are across the political spectrum," Child said.

...Obama and President Bush are 10th cousins, once removed, linked by Samuel Hinkley of Cape Cod, who died in 1662.

Pitt and Obama are ninth cousins, linked by Edwin Hickman, who died in Virginia in 1769.

That's quite a lineage. Impressive.

Obama is not your typical white or black person.
