Hi Gloria,
I don't have your Thomas in my tree, but he is probably related to my Nathaniel (s/o Christopher) b. 1746 Codford St Peter, Wiltshire. Maybe even an older brother. If you go to my tree on Tribalpages and send me a request from there I can give you access to the tree. We may eventually find a link and also find Christopher's ancestors.
Cheers,
Diane
