UPDATE:
Someone found that the children are buried in Berlin. Since Willem Adriaanse his death wasn't found, it is likely they emigrated to Berlin. That makes this a German post as well.
-----------------
In a new blog post, Annemieke van der Vegt, straight male line descendant of an imported slave from Guinee, mentions another person who was also imported to the Netherlands as a slave. Willem Adriaanse (*1823 Den Haag to Maria Calfssnoer). I have found a connection to a wikitree profile, now Annemieke wonders in her blog if there are any living descendants.
Anyone up for a small challenge? It concerns The Hague area.
