She was born in Hollywood, California, to Lillian Carrillo Curry Grey and Robert Earl McMurray,[1][2] and christened Lillita Louise MacMurray.

[8] Still a child of 15, she was initially cast as the leading lady in the film, and then-35-year-old Chaplin started a relationship with Grey.

Grey soon became pregnant, and since Chaplin could have been imprisoned for having sexual relations with a minor, they married that November in secret in Empalme, Sonora, Mexico, to avoid a scandal.

[11] The two had few interests in common, and Chaplin spent as much time as he could away from home, neglecting both his wife and his children, while working on The Gold Rush, and later, The Circus.

[25] She married her fourth husband, Patsy Pizzolongo (aka Pat Longo), on September 22, 1956, in Los Angeles, California.

She died of cancer on December 29, 1995, in Los Angeles, aged 87, and was buried in Valhalla Memorial Park Cemetery in North Hollywood, California.
