Hi Sue,
Many thanks; I checked the register when Iwas on the Island in sept and the entries are inconclusive. Sometimes some registers distinguish between baptism and received into the congregation but German does not in this case. On balance, I would agree it is probably that, but we cannot definitely rule out two attempts at the same name, though I did check burials for the 1803-04 period in case I could "dispatch" the earlier entry with no success. That in my view tilts it towards baptism & received.
