BARACK OBAMA'S ANCESTRY ON HIS MOTHER'S SIDE - Above is a photograph of Barack Obama with his grandparents on his mother's side, Stanley Armour Durham and Madelyn Lee Payne Durham. His grandmother's side of the family can be traced back to my common ancestor, Robert Hudson, who arrived in Jamestown on the ship James in 1622. His grandfather's side of the family came to America some time before 1639 since his ancestor, Jonathan Singletary, was born in Newbury, Massachusetts January 17, 1639. On his grandfather's side, Barack Obama shares a common descent from Samuel Hinckley, who lived in Cape Cod in the 1600's, with President George W. Bush. Obama also shares a common ancestor with Vice President Dick Cheney.
