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.
