Hi Kaz,
The Witnesses might have been friends, but I haven't come across the names in any data relating to Thomas and Phillis which is a shame.
I still might not be 100% sure that the couple is my Gx3 Grandparents, but thanks to your kindness I have learned two extra snippets:-
That Thomas and Phillis DID definitely marry at St. Marys, and that both could write.
I FEEL it is the couple I'm wanting, but that tiny clue I need to make it fact is so elusive, and without that I cannot really claim this couple {though I can keep them on side ;-).
Thank you very much for looking them up for me, I really appreciate all your help.
Sincerely,
Jennyalogy
