Hi, did you get the information from freereg.org? If not, the witnesses to the marriage were Wm Moss and Martha Marshall, and on findmypast.co.uk, since this marriage was by licence, it says they were both of the parish. It might be worth trying to get the licence papers to see the bondsman, who was sometimes a relative.
Have you also found Thomas' remarriage?
Interestingly enough, one of his children was George Branson Redford? They must have been pretty close.
The only Thomas I could find born in 1750 was not in Yorkshire, but for a non-conformist in Nottingham, which was 117 miles away.
