I'm Theresa's mother and wife of Peter Norman Hayton who is related most definitely to your Dad- Raymond Urwin, We tried years ago to find him when we migrated to Australia because Peter was saying that your Dad I think migrated to New Zealand ( that's what everybody thinks)but couldn't locate him. We used to lived in Surrey where one of your Dad's sister Lilly(youngest) lives and so was Norman Hayton. Lilly Urwin Jones passed away last 2004, she has a daughter called Susan whom we still get in contact with and also, there is one sister still alive(not quite sure if she's still alive or not), living in London but not quite sure where and her name is Ann. Susan was telling us about her when Peter and I went to Lilly's funeral. Please get in touch with us as Peter wants to know you.
