My next task - over the coming weeks - will be to locate where they are buried. That's easy if they have a headstone. If they do not I will have to look at the original plot maps I scanned when I visited the church. This is how I worked out where William and Eliza are buried.
I shall then need to start on other names which occur in my tree. The Fletchers and Carters are two families I expect to find as cousins (albeit a few times removed) but I should think I am related to at least 100 folk in the cemetery!
