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 around 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.
Edward's commitment to personal education, along with his wife's position in high society, doubtless contributed to Polly's posh accent and deportment, both of which led Ben Jackson to give her the nickname "Duchess".
- Edward has never been portrayed in performed Doctor Who, only mentioned in passing.
