He's right...that's exactly what the French are today. Mostly descendants of Gauls and Romans...in northern France (except Paris of course...you can find everything there.) you notice that the people look like they may have Gallic origin, and in the south (especially Provence) you see darker, more "Latin" looking people. Of course it's not all inclusive, but for the most part this is true. I'm not so sure if the Franks were more of an ethnic or cultural invasion...probably neither, if i'm correct I think that they just became the ruling caste. Most of the French nobility came from old Frankish warriors and generals.
