Edith Marie Blossom MacDonald (August 21, 1895 – January 14, 1978), also known as Blossom Rock, was an American actress of vaudeville, stage, film and television. During her career she was also billed as Marie Blake or Blossom MacDonald. Her younger sister was screen actress and singer Jeanette MacDonald. Rock is probably best known for her role as "Grandmama" on the 1960s macabre/black comedy sitcom The Addams Family. Personal life Blossom Rock was born on August 21, 1895, in Philadelphia, Pennsylvania. She was the second of three daughters born to Anna May (née Wright; July, 1871 – May 16, 1947) and Daniel McDonald (April, 1869 – August 8, 1924). The family later changed the spelling of their last name to MacDonald. As a youth, Blossom first performed in vaudeville with her younger sister, Jeanette. She had an elder sister, Elsie Wallace MacDonald (1894–1970), who had also been a vaudeville performer and then operated a dance school until 1962. She married actor Clarence Warren Rock, on September 26, 1926, in Manhattan, and they performed as a vaudeville act titled "Rock and Blossom" from 1925 to 1929. Clarence Rock died in 1960, and the couple had no children. Career Rock adopted the name Marie Blake for her film career, beginning as a Metro-Goldwyn-Mayer contract player in 1937 with an uncredited appearance in My Dear Miss Aldrich. Her first credited major part was Love Finds Andy Hardy (1938), and she then played her most notable onscreen role as Sally, the hospital switchboard operator, in the nine films that comprised MGM's popular Dr. Kildare series from 1938 to 1942. She once had the same agent as Irene Ryan, whose similar career later caused Rock to fire him. Rock returned to using her real name in the 1950s, and later gained her biggest fame by playing "Grandmama" on the ABC sitcom The Addams Family, which was originally broadcast from 1964 to 1966. In October 1964, she made a public appearance in character at a haunted house at The Children's Museum of Indianapolis. Illness and death After production on Season 2 of The Addams Family concluded in 1966, Rock suffered a stroke in December 1967 that affected her speech and prevented her from reuniting with fellow castmates for the 1977 television film Halloween with the New Addams Family. However, she watched the film from the Motion Picture & Television Country House and Hospital. She died at
