Forgive me if this starts a war, but is there any good reading or opinions on the historical origins of the Walloons? I know this is kind of a general question, and quite frankly, I'm not sure how far you have to go back to find some continual ethnogensis. But I've always kind of wondered if people who live in the south of Belgium since Middle Ages see themselves as having come from Germanic Franks, French, or Dutch peoples, ethnically?
Like, are they people who see themselves as ethnically old Dutch who were "francized", or people who developed originally in the French sphere of influence and came under rule of the Dutch and then went back to French culture? Any study ever done on the % of "Dutch" surnames found in Wallonia vs. French? I've noticed that it is not safe to assume someone in Wallonia is a Flemish migrant just by their surname, which kind of points to the language barrier having been further south centuries ago?
Or is none of this relevant to the people, today?
