It seems that a link between these two historically important individuals has not been definitively established. Pieter Stoutenburg(h) was a founder of New Amsterdam (NYC) and has an extensive foundation (Stoutenburgh-Teller.com). Johan van Oldenbarnevelt is considered a founding father of Dutch Independence from Spain, and his contemporary Philip De Marnix likely wrote the Dutch National Anthem. The links within the American Stoutenburg lineage are well established, but the links to the aforementioned Dutch figures are not. Is there a way to definitively rule in or out a relationship?
