Harold and Cyril had an older half brother called Charles William, known as ‘Billy’, or ‘Willy’, who had two daughters, Hilda (b.1907) and Kathleen (b.1910). When Hilda was older she kept Gaunt’s shop in Needingworth. She was Harold and Cyril’s niece and they would have known her and her sister as little girls when they were in their teens.
Harold and Cyril lived in Silver Lane with their parents, William and Lizzie (nee Prior), who was his second wife. They also had another brother Walter, who may have been in the Non-Combatant Corps.
