Mary Gertrude (born Anne Greene, 1884–1965), was an Australian nurse and provincial superior, and a member of the Sisters of St. John of God.
Born in Killard, County Clare, Ireland, she settled in Australia around 1905.
She worked as a nurse in hospitals run by her order in Western Australia. In 1929, she began serving at the order's mission in north Western Australia, where she was influential in securing a hospital for Aboriginal Australian patients with leprosy. She cared for patients in the hospital for ten years.
Mother Mary Gertrude was appointed provincial superior of her order in the North-West in 1947, and served two six-year terms. She became a member of the Most Excellent Order of the British Empire in 1948.[1] After her service as provincial superior, she was appointed superior of the Sisters of St. John of God convent in Derby.
She died as the result of a car accident in Broome, on 20 February 1965. She is buried in the Broome cemetery.
