A pair of direct forebears, my 3xgreat-grandparents, eloped in the early-mid 1790s. He, Edward McDowell, had been the family coachman when he ran away with Susan of unknown surname. A 1797 naval record of their residence in Dublin records Susan as Edward's wife. However, a search of 17 collections of marriage records in England (and other collections for the rest of the UK) has not come up with any record of a marriage. Given that neither evidently lived long enough to be recorded in census surveys, a marriage record of some kind is my only hope of finding out Susan's family name - who she was. I'm hoping that someone has some expertise on the role of ship captains in conducting marriages and knows where records of such events would've been filed. For instance, although they may have been recorded in a ship's log, would they have been passed on to the national bureaucracy in some form? Was a marriage licence of some kind necessary?
