I have lots of records that allegedly come from churches in “Montmorency I., Québec, Canada.” I had assumed that the ‘I’ was for Île (Island). But I cannot find such a place in Canada—not even a historical mention online. And it seems that at least two of the churches are on the mainland, with the nearest island being Île d’Orleans. There is a Montmorency Falls nearby, but that’s “chutes de montmorency” in French. A few sources omit the ‘I’, and one says “No 1” (surely incorrectly).
Wikipedia gives some former names for Île d’Orleans but none of them are Montmorency.
Is there something else the ‘I’ could mean? (Maybe I should be looking for a French language stack.)
