Where is map or listing of French place names with old province names?

I want to keep my brother in law's French Canadian ancestors' places of
origin in France with their old province names - as the provinces were
organized before teh Revolution - for correct historical context.

I can't find a map nor gazeteer online that shows teh towns and
villages in their old provinces, and I'm doing alot of guessing. In
many cases, even knowing sort of where the boundaries between the
provinces are, a given village could easily be in either of three
provinces, like Maine or Anjou; Orleanais, Beauce, and Ile de France;
Aunis, Angoumois, and Perigord; Guyenne, Gascogene and Languedoc.
Because current departments and regions often were not cleanly made out
of the former provinces, historical information in wikipedia is often
of little help.

Where can I find the correct information?

In my web site, I give the modern information. You will see for
example Mortagne-au-Perche (Saint-Jean) (Orne : 610293)

Mortagne-au-Perche : this is the town (always the name of today)
(Saint-Jean) : this is the parish
(Orne : this is the departement
610293) : this is a code identifying the town

and a text box. You copy that code to the text box and you press
the enter key. This will give you a lot of data about the town (but
not the province). Near the top, you have this line:

Localisation La carte de Cassini ViaMichelin Locom

La carte de Cassini is a link to a map of the 1700s, but again, no
province.

I think the only place to get most of provinces would be to get the
Tanguay on the Banq web site (it is outdated but give many places
with the original name).
