I am very grateful for the reply postings on this thread and I was hoping that I had found information to allow me to work back another generation.
Having looked closely I now feel that the William Messenger who married Mary Machin on 23 Jun 1794 at Arksey, Doncaster is not in my line of Messengers. The William that I had identified was born on 14 Sep 1763 at Swalcliffe, Oxfordshire.
However identifying this William is dependant upon his son, Benjamin, being the correct Benjamin and I probably need to do some more work to confirm that this is correct. If I make a further query then this will be more appropriate on the RootsChat Durham board.
This part of my tree has been causing problems for some time now and I really thought that I may have sorted it out but it appears that I have not done so, however many thanks for all the reply postings.
Wearsider.
