I'm Portuguese, but I suspect that I am also Flemish because my grandparents come from the Azores islands and I've heard when it was discovered by the Portuguese, it received Portuguese and Flemish immigrants. I also suspect African, North African, and Arabic because not to long after the Roman Empire fell, the African Muslims and Arabs invaded Portugal and Spain, there wasn't very much mixing, but there still was some, so it's probably only a small percentage. I also suspect other European ethnicities, like Spanish, Italian, French, and German because there had to be people moving around the Roman Empire so there had to be some mixing, and after the Western Roman Empire fell, Germanic tribes invaded like all of it. What about you?
