Thank you I will try to bear all this on mind. I have insomnia so now have some info could be up a while.
Robert is a bachelor on his marriage cert.
Apparantly no body messed around ( I am assume with him). There was a story about some false teeth I seem to recall and him or her doing something. I don't think there was much love lost. Nan (beatrice) came to London when she was very young, about 14 so the story goes and did not go home very often. Think she took dad back there dring the war, but never stayed very long.
I know she was scared of one of them, can only assume the Robert that you have found. She never really spoke about them.
If he was that naughty could explain loads i.e the half brother, Tommy. I never recalled him having a welsh accent. Tommy married someone called Pat but for life of me I can not remember his surname. i am sure not the same as nans though. He died n the 1980's in Norwich.
