Wonderful work as always, polarbear!...pleasure to work with you again on such a great hunt!
You're very welcome, penninah

The language wasn't enough of a barrier, messing with the surnames and adding dits and phonetics. ( as you see the dits were used interchangeably or fully whenever ) but the first names being for the most part a religious name which they could keep or discard makes these a real search. One was also at the mercy of the religion when it came to baptisms as some priests/parents/selves probably insisted that all religious ceremony, baptism, marriage, funeral, be entered using the saint's name. This helps explain the different names on census and documents, but makes it almost impossible to wholly prove...
Their proximity in census does help, and the fact that we have no other Nazaire Goodine/Godin on census, but Polarbear has happily found you proof that he was indeed having children between the censuses, when he's been thought not to be alive any longer, proves our theory may be correct, but doesn't prove the whole truth. I have seen many other Isaiah Nazairre and Nazairre Isaiah since, so the names seem a popular pairing.
Polarbear and I are cautious these days as we did find someone many years ago who proved to have a duplicate born in the same place, same year. ( but she'd moved on to another Province with family so didn't show up until we found her death record which had only been made available recently...) The thread-owner had gone on to claim the wrong person and dig in to her ancestors, and we were made to feel at fault...thus our disclaimers below... J.J.
