Résumé : The World Wide Web and digitization have strongly improved the possibilities to search and find. What happens if applying these tools to your family history, leads to the discovery of several ancestors with controversial stories? Think for instance about unexpected stories, ranging from connections to the slave trade in the 18th century, an ancestor connected to a famous gang of 18th-century highway robbers like Jan de Lichte, or a woman condemned and executed after accusations of witchcraft. It raises many questions, but also the challenge for your family or heritage (project): if you do your homework and research, and look far enough, you will find many shades of heritage or genealogies.
