Oh huh, regarding the "joking" use of the simple past and imperative, that's one of the traits of acadian french :p . Mostly when used with the first singular person, which is treated as the first plural person, so you get sentences like "J'avions mangé tcheuques choses...). The "qu" is also sometimes replaced by "tch". :p
Also, not to mention, but most of the territory was explored by French coureurs des bois. <.< How else do you get french names of locations and towns in almost ALL the states and provinces of North America? <.< Obviously, some of them got completly changed, but quite a few retain their french origin. :>
Also, iirc, the conquest of Gaulia had occured around the 1 century before JC, it started in the South, which later became the "Romana Provincia" (which is today's "Provence"
) and a few years later within the century, the people from the south were scared of the northern tribes, so they asked Rome to come help them. Which they did, and conquered the rest of Gaulia. =/ Also, when the first Frank king took over Gaulia after the Roman Empire had fallen, he adopted the local language (which was latin), making the "francique" become a superstrat, instead of imposing it (iirc, he also converted to christianity).
