Cheney and Obama Related?

Think Progress has video of Lynne Cheney telling Norah O'Donnell that Dick and Barack are 8th cousins.

A spokeswoman Lynne Cheney explained to the AP that Obama “is a descendent of Mareen Duvall. This French Huguenot’s son married the granddaughter of a Richard Cheney, who arrived in Maryland in the late 1650’s from England, said Ginny Justice, a spokeswoman for Lynne Cheney.” The Obama campaign’s response? “Every family has a black sheep.”
