Thank you, Trish. I thought Samuel and Jane were on the tree, too.. I actually have a printed article about William Gibson, the mathematician that my grandmother kept in the Family Bible. I am new to RootsChat and hope you receive my reply.
I knew my grandmother very well who was Horatio’s granddaughter and she always claimed she was descended from William Pitt. Certainly cannot confirm this, but have heard the story from other sources, too
