I have looked at the subject marriage record on microfilm last night.Rather hard to read because of the poor handwriting and I am not familiar with the standard formula.However, I do not believe that the parents of the groom and bride are mentioned. But I need a second opinion. IT was customary in those days in denominations other than RC not to mention the parents in marriage records.
John Darby did sign the register. He was a shoemaker is my reading is right.
Will get back to you when I get some help with some deciphering.
