From Earl Woods Entry in Wikipedia:
Earl Woods was born in Manhattan, Kansas. His father, Miles Woods, had five children by his first wife, Viola, and six more (of whom Earl was the youngest) by his second, Maude Carter. Miles Woods was an epileptic who worked as a street cleaner and caretaker. Although he was a devout Baptist, he also had a reputation for being able to swear for 30 minutes without interruption. Earl Woods once remarked, "I picked up on that". Earl Woods' mother, Maude (Carter) Woods was a light-skinned black woman was of mixed African and European ancestry. Wood's siblings ranged from fairly dark to very light; he remembered that his grandmother Carter, a Mulatto, was "the prettiest blonde you ever saw." There was a family joke about an alleged Chinese ancestor who "didn't stay on his railroad job," but there is no record of any Chinese ancestry.
