Hi Hilary, You don't mention where you got these marriages from so I presume they are family marriages and all from Bradford..... Marriages as early as that probably took place at Bradford Parish Church.... ....and I believe they have been filmed by the LDS. I would start there by ordering the films that are needed to check those dates out. There may indeed be an index that would at least verify that the marriage did indeed take place there. Then the PR would give you what was actually entered. My early marriages don't say very much and do not give parents names etc. Just a suggestion. Kindest regards. Elaine Pickard. Ottawa. Canada.
