Mae West's mother, "Tillie", was a former corset and fashion model, and frustrated actress, who had immigrated to America from Germany with her parents. Although Mae West always claimed that Tillie was Jewish, records show that the family listed their religion as Lutheran upon arrival in America. 
Mae was encouraged as a performer by her mother, who, according to West, always thought that whatever her daughter did was fantastic.
Mae West remained close to her family throughout her life and was devastated by her mother's death in 1930.
