Hi Stewart
Many many thanks for checking all that. What a helpful board this is! I hope I may be able to reciprocate at some point.
So it seems that there are several possibilities regarding George Lake: either his baptism didn’t get recorded (by oversight of the minister), or he was baptised at a Non-Conformist chapel perhaps, or he wasn’t baptised at all, or, despite the statements on the census returns and his seaman’s ticket, he wasn’t born on Jersey at all but he assumed that he had been because he grew up there.
Hmm, much food for thought and further research.
Thanks again to everyone who posted.
