I found a strange name on a baptismal record from Biały Kamień which is now part of Ukraine. The records are mostly in Polish and Latin.

It looks like "Nikiefor" but that's a very strange name. I've never seen that name before and I've viewed decades worth of records for the town. Plus there are only 169 results for it on Google.
Extra points if you can tell me what the origin of the name is.
