Does Stephen know his mother's name, if not Cherry?
Does he think his grandad was a Leslie too?
On the original document for the 1911 census it says grandson for 3 year old Leslie but the transcription says son so that's a mistake - so that particular Leslie is a grandson of a George and Jane.

Are you thinking that Stephen's grandparents came from Bridlington, like him, even though his dad was from Norfolk?
