Willie Dean McGee, one of seven children, grew up in a devoutly religious household. His father Hurdice was both a machinist at the Oakland Naval Yards and a deacon in the Pentecostal church. Hurdice did not want his son to play any organized sports on Sundays, so McGee slipped out of the house on Sunday afternoons to pursue his passion for sports. Much later, McGee learned that his father knew that he was sneaking out to play baseball, but decided to let him go on anyway.
