That's really helpful, thanks. I'm puzzled by the Mendelsham details I have. If you have a transcript, could you possibly check if "anyone" was baptised in Mendelsham on 31 Mar 1719? FreeReg only starts about 1749.
Would it be possible to check the marriage of Richard DOVE and Sarah MAYHEW which I have noted as 10 Jul 1745 at Mendelsham.
Thank you for your help
