Keegan-Michael Key
Keegan-Michael Key was adopted at birth and raised in Detroit, Michigan with his adoptive family. Like his birth parents, it was an interracial marriage. These parents later divorced, although his father remarried. When he was 25, Keegan Michael was finally able to meet his birth mother, who revealed that he had two siblings, one of whom was a famous comic book author Dwayne McDuffie. Sadly, they had already passed away at that point.
Gerald R. Ford
Some people are born into greatness and others have greatness thrust upon them. At age 12, the young president discovered the truth of his parentage, his "father" was actually his stepfather and had legally adopted him when he was young. He also learned that he once went by a different name. He was once named Leslie Lynch King Jr. but was renamed after his stepfather, Gerald R. Ford Jr.
