Never mind Brad Pitt or Warren Buffett.

President Obama has found another long-lost cousin: Scott Brown, the Republican state senator from Massachusetts who won the Senate seat long held by the late Sen. Edward M. Kennedy.

The president and the senator-elect from Massachusetts are 10th cousins, according to the New England Historic Genealogical Society.

Experts there report that Obama’s mother, Stanley Ann Dunham, and Brown’s mother, Judith Ann Rugg, both descended from Richard Singletary of Haverhill, Mass. He died in 1687 at 102.

Obama descends from Richard’s eldest son, Jonathan Singletary, who later changed his name to Dunham. Brown descends from Jonathan’s brother, Nathaniel Singletary.

In 2008, the society discovered that Obama is related to seven previous presidents, including George H. W. Bush, George W. Bush, Jimmy Carter, Gerald Ford, Lyndon Johnson, Harry S. Truman and James Madison. They also learned he was related to actor Brad Pitt and investor Warren Buffet.

Brown will be sworn into the Senate in February.He’ll surely be inviting his family.
