The daughter of a London retail draper, Marion Davies won a National Skating Association gold medal in 1944, and the following year finished third behind Cecilia Colledge and Daphne Walker at the British Figure Skating Championships. She never won a British title, and was runner-up again, to Walker, in 1946, and to Jeannette Altwegg in 1947. Internationally, Davies competed in the European Championships in 1947 and 1948, and the Olympics and World Championships in 1948, with a best finish of seventh at the 1947 Europeans. Davies turned professional after the 1948 London Olympics, and joined the famous Ice Follies, working all over the world. In the Winter months, she taught skating at St. Moritz, and in the 1960s went on a three-year world tour with her ice show.
