The brother of James and son of Arthur and Mary Sproson, Harold was born in Wolverhampton in 1889. The family were at 102 Owen Road, Wolverhampton, in 1901. By 1911, he was living with his parents and sister Edith Nelly at 53 Kimberley Street, Wolverhampton. He had become a butcher.
Unlike his brother, however, Harold does not appear to have served in the army. He was, however, on the list of Special Constables employed by Wolverhampton Borough Council during the First World War. He survived the war, and traded as a butcher from 61 Owen Road, Wolverhampton, until at least 1940. He married Edna M. Wootton in 1936. The couple appear to have had three children – Ann and Timothy (born in 1942 and presumably twins) and Lynn (born 1947). Harold died in Wolverhampton in 1969.
