Moore was born Demetria Gene Guynes in Roswell, New Mexico. As a child, Moore had a difficult and unstable home life. Her biological father, Charles Harmon, left her mother, Virginia King (November 27 1943 – July 2 1998), after a two-month marriage, before Moore was born. As a result, Moore had the surname of her stepfather, Danny Guynes (March 9 1943 – October 1980), on her birth certificate. Danny Guynes, who committed suicide in 1980, frequently changed jobs; as a result the family moved a total of forty times, once living in a small town called Rogers Manor, Pennsylvania. Moore's parents were alcoholics and often fought and beat each other. Moore was cross-eyed as a child, and wore an eye patch in an attempt to correct the problem until it was eventually corrected by two surgeries. She also suffered from kidney dysfunction.[1] Demi Moore has heterochromia; she has one green eye, and the other hazel.
Moore's family settled in Los Angeles in 1976. Moore attended Fairfax High School in Hollywood, where her schoolmates included Red Hot Chili Peppers frontman Anthony Kiedis and bassist Michael Balzary and actor Timothy Hutton. When Moore was sixteen, her friend, actress Nastassja Kinski, persuaded her to drop out of school to become an actress.
Moore has two younger half-brothers: James Craig Harmon (paternal) and Morgan Guynes (maternal, born 1967). (wilkipedia.org)
