Dr Edward Wright was the father of Polly Wright. He had one elder brother, Charles, and a younger brother, Randolph. He married a socialite, Miss Bettington-Smith, in August 1939. Soon afterwards, she gave birth to a boy. In 1942, Polly was born, by which time they were said to be living in a "big, old house in the country." As of 1944, Edward's mother was still alive. Some time after Polly's birth, Edward and his wife had three more sons. As a young adult, Polly reflected on her parents and admitted that she had taken them for granted but they had always been there for her.
