Donna Corcoran

Donna Corcoran is an American former child actress who appeared in nine Hollywood films from 1951 through 1955. She was in two aquatic musicals that featured Esther Williams (portraying swimmer Annette Kellerman as a child in one), and as a vulnerable girl being victimized by an emotionally disturbed babysitter (played by Marilyn Monroe) in Don't Bother to Knock. After making her last film, she made a token comeback as a young adult in an episode of the long-running sitcom My Three Sons (starring Fred MacMurray) in the early 1960s. Corcoran was born in Quincy, Massachusetts to William Henry Corcoran, Sr. and Kathleen H. McKenney. Several of her siblings were child stars, including younger sister Noreen Corcoran, Kevin Anthony Corcoran, and Kelly Corcoran.
