Thank you for your post Highclere. The details that I have for David and Sophia where already on a family tree that my mother got off her brother, which he found 2 years ago amongst his mothers belongings after she died. He knew nothing of the families history until then.
No one knows where the details have come from as there is no reference number for David or Sophia. That is why I am trying to confirm these details. Hence, the hesitation about Davids parents.
I'm also sorry that I don't have any marriage details for them either. All I know are the details that I posted. I'm looking everywhere for more details about them but it is a slow process. If I find out anything more I will let you know.
