Hi,
I don't know if this information will be any help or not but it may find you a contact to help you get further back!
I was born in the village of Coltishall (next village to Horstead) & lived next-door but one to a Jack & Iris Bunting who had two daughters, Wendy (now deceased) & Irene.
Jack had a brother in Horstead (?name) who was married & had a large family, Robert, Brian, Beryl, Trevor , Roger, Brenda, Daphne, Peter, Paul, Avril, Eamon & Adrian! They will have been born in the 1940s & 50s. If you could find any of them, they may be able to help. Jack & his brother both worked at Coltishall bakery. Iris is still living so far as I know.
Happy hunting!
Holly Bush
