1911 Lucille Ball – Comedienne and actress (I Love Lucy, The Lucy Show, Yours Mine and Ours, Mame, Stage Door) She starred as a ditzy wife in the radio show My Favourite Husband. When CBS decided to launch the popular series on the relatively new medium of TV, Lucy insisted her husband Desi Arnaz be cast as her husband in the TV version. The network executives argued that no one would believe the couple were married, but Desi and Lucy performed before live audiences and filmed a pilot, which convinced network executives that audiences would respond well to their act
She did a Marx Brothers movie and some stuff with John Wayne, but I still never really liked her.
1917 Robert Mitchum - Actor (The Sundowners, Cape Fear, Scrooged, The Winds of War, The Big Sleep, The Friends of Eddie Coyle, Out of the Past, The Longest Day, El Dorado) He was the brother of actor John Mitchum
He is also Christopher Mitchum's father. I don't know what else but Christopher was in several John Wayne movies.
