When is a Quebec "Comté" not a County?

I guess one learns something important every day...

I thought I'd post this here, because it drastically affects one's ability to correctly cite a Quebec Church record.

I hope it helps someone else.

A subtle but important point in Quebec genealogical history:

In the mid-19th century, parish registers often used the word comté (“county”) in headings or descriptions, but in some cases — especially in church contexts — it really referred to an ecclesiastical division (a deanery) rather than a civil county.

Until now, I could never get the county geo-location correct in my records, because I was using the "Comté" stated on the first page of a register. In fact; that "Comté" is more a part of the address; as in "St.-Joseph-de-Soulanges Church, Vaudreuil Deanery" located in the place, "St-Joseph-de-Soulanges Par., Soulanges Co., Canada East, British North America", in 1855.
