One of the soldiers sent to the U.S. by France during the French and Indian Wars
is listed as Monsieur Carlan.
The surname was CARLAN.
The non-de-guerre was listed as MONSIEUR.
Monsieur Carlan was a member of Berry Company, one of several companies that
served the French cause in this war. (The result of the war, incidentally, was
to establish British authority in the New World, and eliminate French authority.

I know nothing more about Monsieur Carlan other than what's stated here. The
