Mary Carr, was an American film actress and was married to the actor William Carr. She appeared in more than 140 films from 1915 to 1956. She was given some of filmdoms plum mother roles in silent pictures, especially Fox's 1920 Over the Hill to the Poorhouse, which was a great success. She was interred in Calvary Cemetery. Carr bore a strong resemblance to Lucy Beaumont, another famous character actress of the time who specialized in mother roles. As older actresses such as Mary Maurice and Anna Townsend passed on, Carr, still in her forties, seem to inherit all the matriarchal roles in silent films.

Calvary Cemetery is a Roman Catholic cemetery that the Archdiocese of Los Angeles runs in the community of East Los Angeles, California. It is also called "New Calvary Cemetery" because it succeeded the original Calvary Cemetery, over which Cathedral High School was built.
