Born in India, Nora Polley lived in Scotland by 1901, and was educated at Hillcote Boarding School in 1911. She married Sydney Trepess Polley, a military officer in the Indian Army, who became a major in 1918. She played at Cannes early in 1924, and then competed in the 1924 Olympic tennis tournament. Polley then played a series of tournaments in the south of England later in 1924, which included the Tunbridge Wells Tournament, the Hastings Tournament, the South of England Championships, and the Weymouth and Torbay Tournaments. There is no record of her playing again after 1924.
