Thanks for all your efforts!
This is him on the electoral roll. It’s the same address as the 1939 register.
Yes we think Lawrence and Pamela are twins too. There are two closed records on the 1939 document which is likely to be them, since they would have been around 9 at the time.
He had twins with his first wife Catherine, though neither survived more than a few hours.
Many thanks, you’ve given us some new clues to work with!
