Mary Margaret Wood (February 9, 1892 – March 18, 1978) was an American actress of stage, film, and television. She is best remembered for her performance as the title character in the CBS television series Mama (1949–1957), for which she was nominated for a Primetime Emmy Award for Outstanding Lead Actress in a Drama Series; her starring role as Naomi, Ruth's mother-in-law, in The Story of Ruth (1960); and her final screen appearance as Mother Abbess in The Sound of Music (1965), for which she was nominated for an Academy Award and a Golden Globe Award.

Peggy Ann Wood (14 June 1912 – 30 May 1998) was a British actress, director and theatre manager associated heavily with the Bristol Old Vic. In partnership with her husband, Ronald Russell (1910–1994), she ran the repertory company the Rapier Players, based in Bristol's Colston Hall. During the Second World War, Peggy Ann Wood ran the theatre whilst Ronnie served in the Police War Reserves, and once the Prince's Theatre had been bombed in November 1940, the Rapier Players provided the only live theatre in the city of Bristol. The contribution of Ronnie Russell and Peggy Ann Wood to the theatrical heritage of Bristol was commemorated with a Blue Plaque Ceremony in July 2002, which is situated on the outside of Colston Hall, Bristol.
