Since a long time Schuncks were weavers. If this was the case in Oppendorf near Cologne too, is hard to say. Nikolaus Joseph Schunck, who died 1776 in Kettenis near Eupen (Belgium), was a weaver for sure. So was his grandson, Nikolaus Severin. He was the last common ancestor of the Dutch and the Belgian Schuncks. He expected his sons to join his shop, but only Severin Joseph did so. The first son, called Nikolaus of course, went to the weaving mill Delius in Aachen, Germany.
Later he and his brothers Wilhelm and Ludwig, and for some time Arnold too, went to Bealistok, in the russian part of Poland. They had been invited to modernise a weaving shop. We have heard that some Schuncks lived there until the end of World War II, but we don´t have any further information.
