Ann Dunham
In 1995 in Hawaii, she died of uterine cancer which spread to her ovaries. Following a memorial service at the University of Hawaii, Obama and his sister spread their mother's ashes in the Pacific Ocean at Lanai Lookout on the south side of Oahu. Obama scattered the ashes of his grandmother (Madelyn Dunham) in the same spot on December 23, 2008, weeks after his election to the presidency.
