jimgordo1,
The Gordon burials are much later than 1630s - 1715. I only have the Penninghame Old Kirkyard MI's. The MI stands for Monumental Inscriptions - lists all the burials that have headstones, in that cemetery.
As I am not from this area, I do not know of other cemeteries . You mention Kemmure in your first post, there maybe a cemetery there.
Just a thought, there is a possibility your ancestors were buried without a headstone, and may never find their burial place, as with my GGG Grandparents.
Sorry I wasn't able to help. Good luck with your search.
