American character actress famed for roles as mothers. Born in a Philadelphia suburb as Mary Kennevan, she became a schoolteacher, but soon gave it up for work as an actress in touring companies. She married actor William Carr and toured extensively with his company. After the turn of the century, he became involved in film production as both an actor and director, and he brought Mary and their six children into the film business with him. Mary made her film debut in 1916, but it was her appearance in Over the Hill to the Poorhouse (1920) which made her a success in movies. It was a tremendous success due in large part to her touching portrayal of a poverty-stricken mother. She followed it with similar roles in scores of films throughout the silent period. A fallow period arrived with the talkies, and Carr found herself nearly destitute, but publicity about her status rallied help to her cause and she found help and occasional work. She spent her later years appearing infrequently, often in films directed by her son Thomas Carr . She died at the age of 99 in November 1973.
