Hi
Are these actually St Mary's church and church yard? I think from the date that they must be, because it's before the cemeteries were open.
If that's the case, I've been looking at a couple of these nyself. Most of the stones have been moved, though some are incorporated in the paving. Many of the ones inside have been covered uip.
However, I've been told there is a transcript. I just haven't had time to follow it up yet. When I do - hopefully in the coming few weeks or even days, if you don't have it, I will look yours up as well.
I hope we can help.
Best wishes
Emms
