Was my ancestor a prostitute in the low countries? If he or she was than chances are that you could find them as long as you know where to look. In this presentation I will give an overview of “hiding places” of prostitutes and brothel keepers that can be found in Dutch and Belgium archives. The presentation will also focus on the reliability of these resources. And, finally, the stories of the people involved are set in the context of the changing 19th century prostitution market.
