7. Bill Clinton
Bill Clinton is only the second president in US history to have been adopted (Gerald Ford is the other). He was born William Jefferson Blythe III in Hope, AK, in 1946. His father died in an accident three months before his birth, and his mother moved to New Orleans to study nursing, leaving her baby boy with family members. He was raised by his grandparents, Eldridge and Edith Cassidy, until his mother returned four years later. She married Roger Clinton, Sr., who adopted Bill as his own.
