Evin Harrah Cosby was born in 1976 at Cedars of Lebanon Hospital in Los Angeles, California, to Bill Cosby and Camille Hanks Cosby.
Erika Ranee, Erinn Chalene, Ennis William, and second-youngest Ensa Camille are her older siblings (in order of birth). Evin’s middle name was inspired by her father’s close friend William Fisk Harrah.
Family friends Tina Turner and Diana Ross babysat Bill’s daughter in their dressing rooms when he was a child. Evin started primary school at Banks Street Elementary, a private school in New York when she was five years old.
She subsequently changed schools and enrolled in Columbia Grammar & Preparatory School, the oldest non-religious private school in New York that offers kindergarten through grade twelve. Evin enrolled in Spelman College in Atlanta, Georgia, after finishing high school. Black students have historically received assistance from Spelman College.
