Mrs. Cheney's spokeswoman Ginny Justice gave CNN's Ed Henry more details, saying the two unlikely relatives are related through a French Huguenot named Mareen Duvall. Cheney and Obama are both descendants of her.
According to Justice, the vice president is related to her through "the first" Richard Cheney, who came to America in the 1650's. His granddaughter married Samuel Duvall, son of Mareen Duvall.
Obama is related to Cheney through Mareen Duvall, a 17th century immigrant from France.
Mareen and Susannah Duvall were Obama's great-great-great-great-great-great-great-great-great grandparents and Cheney's great-great-great-great-great-great-great-great grandparents.
