The couple had a son Christopher, but their marriage lasted less than a year before they separated. Cradock left her son Christopher and husband Arthur for a new life in Central London. Christopher was brought up in Norfolk by his father, an aunt and grandmother, although he made contact with Fanny in his adult life. Arthur Chapman became a Catholic and so would not give Fanny the divorce she later requested, as it was against the teachings of the Catholic Church. He was given only a single line in Fanny's autobiography.
