I'll put that on my list for when I next get to the Island. I'd be even more puzzled if the register did actually say John rather than Thomas as the only mention I can find of a John is in the 1841 census. Can't find John, Thomas or William in 1851, but then I can follow Thomas son of William through from his marriage in 1855 to what seems to be his burial in 1879. There doesn't seem to be a burial for a John, or a William of the right age for that matter.

Thanks Frances.
