I cannot find the 1955 London electoral register on line
The dates I have asked for are the actual dates so the 1955 and 1956 Hertfordshire electoral roll for Stevenage is what I am looking for.
You have what you need in London from October 1954 and 1955, in Friern Barnet and Wood Green, the electoral registers for 1955 and 1956.
So how could your man be on the electoral register in Stevenage as well?
I have an official document (post office savings book) in which my father lists 42 Elbow Lane as his address in June -July 1955.
Again, he shouldn't be on the electoral register twice?
I contacted the Herts archives and they said they do not have the electoral years I want
They have Hitchin Division 1953, 1954, 1955, 1956.
