Born Edith Blossom MacDonald, Marie Blake started out as a child performer in vaudeville, singing with her younger sisters Jeanette and Elsie. In 1926, Marie married song-and-dance man Clarence Rock, forming an act that endured into the 1930s. When vaudeville died, Marie and Clarence went "legit" in straight drama. While playing a consumptive prostitute in the Los Angeles company of Dead End, Marie was spotted by an MGM talent agent. Since sister Jeanette was already an established MGM star, the studio decided to avoid accusations of nepotism by changing Marie's last name to Blake. Never a leading lady, Marie remained a reliable member of MGM's featured-player stable for nearly ten years. She played hospital receptionist Sally in 13 of the studio's Dr. Kildare entries, and also showed up in such short subjects as Our Gang's Alfalfa's Aunt (1940). Loaned out to RKO in 1944, she enjoyed one of her meatiest roles as Harold Peary's vis-a-vis in Gildersleeve's Ghost. From 1957 onward, Blake acted under her married name, Blossom Rock (her husband, who'd retired from show business to work as night manager of the Beverly Hilton, died in 1960). Marie Blake/Blossom Rock's last major assignment was as Grandmama in the TV series The Addams Family (1965-66).
