You really have dutch ancestry? how do you know? northeast Brazil or Olambra? I've always heard tales of having Dutch ancestry too, but my "Brit isles", former central-west euro, is probably my azorean side, flemish, as I have seen in my family tree that I have Van der Haegen (da Silveira) among other surnames..
I wonder if that could be a combo of Flemish and very little Dutch, because 21%, or 23 as it was is very a very big chunk..
