Sjoerd van der Molen is a Dutch writer with Frisian roots. Born in 1957 in Heerenveen, he is a technical engineer with a rich background in both engineering and information technology. For many years, he conducted genealogical research, primarily focused on tracing the ancestors of emigrated Dutch people and Friezen om Utens (Frisians abroad) in countries such as Australia, Canada, and the United States. With a passion for history and family stories, his work has led to numerous discoveries.

He is the author of "Grietmannen van de Zevenwouden", a genealogy and historical exploration of two Frisian magistrates, father and son, and their role in the district of Aengwirden in the Zevenwouden region (available only in Dutch). He also wrote "Prisoner in Schnuttenbach and Democracy".
