Good question. Tbh, that seems to be a general assumption by other tree owners. Since my original post here, I now think he might have been baptised in St Luke, Finsbury. If you can, pls take a look at our tree (HamiltonSawyer) on Ancestry, where I have done quite a bit of research into Samuel Sawyer b. 1739. I'd be pleased to receive any further information on this chap.
