There is a book about the Perry family of Essex during this period. It makes for a really interesting social history. My own branch of the Perry family were from that area, but moved into London for work. My paternal grandfather (George Perry) worked at the railway engineering works at Stratford, London and lived in a rented house (now demolished) in Salway Road, Stratford. His wife was Ellen (who was born just within the reign of Queen Victoria) and his only son, George Arthur Perry. George married Iris Lilian Curtis (They were both born in 1927) and they had two children and adopted one, myself. They lived in Barking, Essex and in the 1980s moved to the village of Ingrave, close to Brentwood (of which Shenfield forms a part) in Essex.
We discovered that there is a 'Perry's field' not far from there. Our neighbour came across the book and I'm trying to locate the title online, but just keep getting stuff about Sarah Perry's famous novel 'The Essex Serpent' - now an Apple TV series. She's from further out in Essex and I don't know if that's her married name or if she's any relation - will have to ask her. I've read three of her books.
The Perry family seem to have had a tradition of calling the oldest son George. We moved to Brentwood because my mum was evacuated there during the war and liked it and one day she took the wrong turning coming home from work and ended up there and got the idea of moving there. My older sisters are still there in Shenfield and Rayleigh, but I moved to Bath. Not sure if all this is any help - I'm not good at dates. See also,
