Diane Keaton and Michael Keaton Family Trees Compared: Genealogies, Birth Names, and True Origins
To understand the Diane Keaton family tree, you have to look west. Born Diane Hall on January 5, 1946, in Los Angeles, California, she was the eldest of four children raised in Highland Park and Santa Ana. Her father, Jack Newton Hall (1922, 1990), was a civil engineer and real estate broker of English, Irish, and German ancestry. Her mother, Dorothy Deanne Keaton (1921, 2008), was an amateur photographer and homemaker who was crowned "Mrs. Los Angeles" in a local pageant, an event that profoundly shaped Diane’s artistic worldview.
Diane grew up alongside three younger siblings: brother Randy Hall, whose personal struggles she chronicled in her moving 2020 memoir Brother & Sister, and sisters Robin Hall and Dorrie Hall. When Diane joined Actors' Equity Association in New York during the late 1960s to appear in the original Broadway run of Hair, she discovered another working performer was already registered under the name Diane Hall. Honoring her mother's heritage, she claimed Dorothy Keaton maiden name as her professional identity. Her birth name never truly vanished, however; Woody Allen affectionately retained her original family surname when writing the titular character of Annie Hall.
