It is estimated that more than 20,000 Dutch entered Brazil, however, both groups had been forced out of the country after the rule's end. The remaining families mostly fled to remote parts of the interior of Northeastern Brazil (mainly in the states of Pernambuco, but also Paraíba, Rio Grande do Norte, Ceará and others) or changed their names to Portuguese ones. The proven excess of Y-chromosomes of the haplogroup 2 in northeasterners probably results from the high miscegenation of Dutch settlers with the local population.
