I think this is the marriage of John Bingham (son of Rt Hon Henry and Anne Vesey) and Frances Elizabeth Shaen in 1737, they being the parents of Henry who married Letitia Daly in 1761,the parents of my Major Denis, his brothers Henry and John. You are right parent details are a little scarce, may have to order the complete details from one of the ancestry sites to find wife of Denis and/or mothers details for birth of William, however still can't find his marriage location or date (had thought William's wife was Maria Houston but I have found no documents to prove the information) This is a very difficult part of my ancestry to find.... however thanking you guys for your contributions
