Send a message to the person who requested a photo of the grave monument of Thomas Clements with the following comment:
I think the transcription of the burial years for Thomas and Elizabeth Clements is incorrect. The burial years 1834 and 1837 should be 1854 and 1857. A similar website to yours called interment dot net lists the same people in the All Saints churchyard but with the correct years. I'd give you the url but the webpage won't allow it to be embedded. Cheers, Bill
