Could the note refer to a place name?
For example, before 1813 the register for a church in village X may not show any address for families who live in X, but if they come from a nearby place Y (which perhaps does not have its own church), the register will show the name for Y after the names of the parents. Usually this is written in full, but perhaps not in the register you refer to. Or is it a transcription, rather than the original register?
