Where did this elite lineage stem from?

According to the New England Historic Genealogical Society in Boston, Middleton is an eighth cousin eight times removed to George Washington. Their common ancestor, Sir William Gascoigne, died in 1487.

William's late mother, Princess Diana, and great-grandmother, the Queen Mother, also were Washington's cousins.

It doesn't' stop with Washington, however, Middleton's other American relatives include explorer Meriwether Lewis, who teamed with William Clark for their renowned 19th-century Western expedition. He's a ninth cousin seven times removed. Like her relatives, travel and adventures are sure to be on the horizon for Middleton.

The society also says Middleton is a 13th cousin three times removed of World War II General George S. Patton.

So have Prince William and Middleton's ancestors crossed paths? Technically, the two are 15th cousins, through Sir Thomas Fairfax, who died during Henry VIII's reign. Good thing so much time has passed!
