Walter has a brother Harry on the Connah’s Quay & Shotton Cenotaph. Harry has his own page on this website. I think they were twins. They were registered at Hawarden with only 1 digit difference in their reference numbers.

Walter was named on 2 other memorials – the Connah’s Quay War Memorial and possibly on the memorial screen at St Ethelwold’s Church. Somebody made an effort to ensure he was remembered.
