I do not know if this might help but I have a card for Grizzel Wishart.Her marriage details were recorded in 2 parishes, Coldingham parish in Berwickshire on 1 Aug 1746 and Dunbar parish (some 30 miles North and on the coast of the Firth of Forth) on 25 Jul 1746. This indicates that one of the couple came from Dunbar.
Ihave no more data on her and ditto for Paul Johnston.
If you know her birth or baptismal dates or parental details, etc I would be pleased to record them.
They are not in my tree.I collect Wisharts and have more than 16000 of them.
