Thank you all so much for your responses. Sorry that I haven't been back....busy with visitors.
You have given me a lot more info for my notes & to ponder on.
However, I was hoping that this post might put me in contact with some descendants of this couple, as of a large number of possibles to fit in my son's tree, these seem the most likely, and I was hoping to save myself a fortune in certs, by making contact with someone who can confirm or discard my research.
Looks like I will need to spend up and hope.
Thanks again.
Blessings
