Dennis was born in Walsall on 13 May 1886, the son of John and Jane Bill. By 1901, he was living with his grandmother and brothers Henry J. and Walter F. at 51 Wednesfield Road, Wolverhampton. He was working as a railway clerk. By 1911 he was listed as a visitor in the home of his uncle, George Charles O’Neal, at 7 Springfield Road, Wolverhampton. Dennis was now working as a grocer’s assistant. Later that year, he married Emma Jones in Wolverhampton, and they had a daughter, Constance, in 1912.
Dennis does not appear to have done any military service during the First World War. However, he served Wolverhampton Council as a Special Constable. Unfortunately I have not been able to confirm further details of Dennis’s life.
