The 1060s invasion had barely anything because it barely involved anyone, as did the further Angevin invasion just decades after. Settlers (in majority from other regions of France btw, not that Normandy is anything different) came over the following three centuries, but even them were not numerous enough to change much of our ancestry. In any case the idea that Normandy was some sort of secret Denmark in completely goofy and retarded beyond measure.
