Molly O'Day was an American film actress and the younger sister of Sally O'Neil.
Born as Suzanne Dobson Noonan in Bayonne, New Jersey, her first appearance was in the Laurel and Hardy short 45 Minutes from Hollywood in 1926. She also appeared in Hal Roach's Our Gang series, and like her sister became one of the WAMPAS Baby Stars in 1928. After appearing in a few dozen films in the 1930s she retired.
Only 16, she defeated 2,000 contenders in an audition for the tough girl heroine in the 1927 prizefighter movie "The Patent Leather Kid." That role led to major roles in "The Lovelorn," "Hard-Boiled Haggerty," "Shepherd of the Hills," "The Little Shepherd of Kingdom Come," "Show of Shows," "Sisters," "Hired Wife," "Gigolettes of Paris," "Skull and Crown" and other features.
Born Suzanne Noonan, O'Day was the youngest of 11 children of Metropolitan Opera singer Hannah Kelly and Bayonne, N.J., Judge Thomas Francis Patrick Noonan. After their father's death, O'Day and her two sisters moved to Hollywood. One of the sisters became an equally successful actress, Sally O'Neil, who died in 1968.
