The first name on the war memorial, George W. Hargreaves, is not on this list. He was apparently in the RAF, and died in Blackpool on 23 September 1919. The Guild Secretary presumably felt that he hadn’t actually died during the war.
The twelve names listed are:
Alfred Coles King’s Liverpool Regt.
Arthur M. Cross Royal Air Force
Duncan Clarke Royal Air Force
Joseph Dewhurst Liverpool Irish
Henry Howarth Lancashire Fusiliers
Ben Riley Royal Welsh Fusiliers
Arthur Sykes Liverpool Irish
Harry Sykes Liverpool Irish
