Marion Orme Page (nee McPherson) (1918-2015) was born in Armadale, Victoria, to Sir Clive McPherson (1884-1958) and Lady Sidney Marion Orme Isabel McPherson (nee Wolfenden) (1879-1946). Educated at Toorak College, Frankston, and The University of Melbourne (initially as a resident of Janet Clarke Hall and later as a non-resident student), she obtained a Bachelor of Laws in 1940 and was the first female articled clerk at Mallesons, Stewart & Co. After practicing as a lawyer, she enrolled in the Women's Auxiliary Australian Air Force (W.A.A.A.F) and had attained the rank of Section Officer when she was discharged in 1947. Marion was later employed as the personal and private secretary to Lady Violet Brooks, the wife of Sir Dallas Brooks, Governor of Victoria 1949-1963, and assisted Lady Brooks during Queen Elizabeth II's 1954 Royal Visit to Australia. After her mother passed away in 1946, Marion assisted her father with the family's agricultural properties - especially Tarramia, near Mulwala, which she purchased from the Estate of Lady Sidney M. O. McPherson in 1954 and held up until her death in 2015. She also accompanied him on overseas trips. In 1960, Marion married Dr. Julian Orm Smith, a surgeon at the Royal Melbourne Hospital. After his death in 1971, Marion re-married in 1975 to Brian Page. Following in her mother's footsteps, Marion was involved with the Ministering Children's League - the charity that runs The Cottage by the Sea, Queenscliff. She was also on a series of management committees for the Royal Melbourne Hospital and involved with other charitable organisations such as The Lady Gowrie Child Centre, the Women's Committee of the Cancer Campaign, and the Red Cross.
