Thanks to you both for this information. It is the very first thing I have ever found out.
My husband is sure that Ivy was older than his mum Joyce. Don't know if Ivy had another christian name.
All he remembers about Ivy is that when he was a little boy pre school age and he was born in June 1953, was that she came to stay with Joyce, Norman and the two boys Kevin and Michael. She had no one with her. There seemed to be some trauma. He does not know how long she stayed but one day she went out and was never seen again. Joyce tried to find her, following some false leads, but after that, nothing............ My husband thinks that Ivy was special needs, thought to have been that way following a childhood accident. There is no one that we know of from that family.
