Flemish, Alsatians and Corsicans are literally Dutch, German and Italian, who are just part of France due to recent history. Occitans and Catalans are near Spain.

Bretons are Celts just like Gauls, whom you missed. You also missed other Celtic groups. And they (Celts) were the majority before invasions, still the majority.

Indigenous doesn't mean minority, it means the original inhabitants.
