Hi Jan,
Pleased I've been of some help, I don't know whether I will ever find the answers to what I am looking for but here is my Mother's story:
My Grandma nursed in Stoke Mandeville Hospital during the Second World War, she had a relationship while she was there with an orderly called Alfred Tomlinson. My Mam was the result of that relationship. When my Grandma came home after the war I know they kept in touch for a while, Mam remembers he sent postal orders for her. Over time the communications stopped, his last known address was in Dewsbury. I have found out that he died in 1975, Mam has always wanted to know if she has other family, as she is an only child and my Grandma never married. However, she didn't want to upset anyone if she searched and had found out that her Dad had married and had a family of her own. (Is this making any sense??) So I am trying to find what information I can about a family she never knew and never will know. She has been over the moon with what I have found so far, but the man she really wants to know about (her Dad) remains a mystery. I have recently applied for his death certificate so I am waiting to see if that brings any new information.
Good luck with your own research, it is certainly interesting and addictive but it can be painful at times.
kind regards Andrea
