I assume Gallia has citizens of all of the Francophonie aboard, just as Bretonia probably has a lot of commonwealth citizens.
Niger, Benin, Mauritania, Vietnam, bits of India, Syria, Papua New Guinea, all examples where people could come from outside France. It makes sense too, because a genetically homogenous population would die out. Gallia is also huge and each planet would have differentiated substantially in regions over a thousand years, in language, biology and local culture. Are Spanish the same as Visigoths?
