Popular Actress of Republic Pictures' B-movie western films of the 1940s.
She fell into acting after deciding on a lark to take an acting class in Los Angeles, and a neighbor in Atlanta, where she lived, helped her get cast in the 1937 film Wells Fargo.
She often played the tough Western heroine in a time when many actresses were stuck playing the damsel in distress.
Her parents divorced when she was young, and her mother remarried, giving Peggy O'Rourke her last name of Stewart.
She played the grandmother of Jenna Fischer's character, Pam Beesley, in two episodes of The Office, the long-running NBC sitcom.
