Kris, thank you so much, you are very kind to have researched this, I wasn't expecting such interest or such a result.
We too were thinking there were two men of the same name after being puzzled by the age differences and the marriages. We initially wondered if our grandfather had had a secret family somewhere! My grandmother (his daughter) and her two brothers are now deceased, we are constructing a family tree, and are having to dig for information ourselves.
It's all becoming clearer now, thanks to all of your input, thank you all.
Information on this bloodline has been vague to us as my grandmother and her brothers became estranged from their father.
Thanks again to you all,
kind regards,
Claire
