Hi Jo,
It seems you are talking about my Aunt, Margaret Bell Ferguson Renton. She was born about 1920. Her parents were Alexander & Margaret Ferguson Renton, both deceased and both from Scotland. My Mother, Elizabeth was Margeret's sister. My sisters and brother and I had never heard that our Aunt had a baby before she was married so this is a surprise to us. Of course things back then were kept secret. I did not stay in touch with my Aunt and have been trying to contact her, I am not sure sure if she is still living. I understand that she married a Frederick Hooper-Greenhill in 1948. They had two children who may live in Wiltshire. What happened to Marilyn? I would like to be put in touch with her.
Thanks, Julia
