1955
Barbara Mullen (9 June 1914 – 9 March 1979) was an American-born actress well known in the United Kingdom for playing the part of Janet McPherson, the housekeeper in Dr. Finlay's Casebook. Although the role of Janet brought her fame in later years, she already had made her mark in the theatre. Mullen's parents were Pat and Bridget. Pat was from a fishing family on Inishmore island off the coast of County Galway, Ireland. Wikipedia
