Our adventure in the Netherlands continues with a quest to find the Walloons, the French-speaking religious refugees who became the first settlers of New Netherland in 1624. Their descendants would last well beyond the existence of New Amsterdam and were among the first people to become New Yorkers.

But you can't tell the Walloon story without that other group of American religious settlers -- the Pilgrims who settled in Massachusetts four years earlier.

All roads lead to Leiden, the university city with a history older than Amsterdam. Greg and Tom join last episode's guest andrews.academia.edu/JaapJacobs">Jaap Jacobs, the author of The Colony of New Netherland, to explore the birthplace of Rembrandt, the historic botanical garden and a site associated with Adriaen van der Donck (whose "patroonship," or manor, gives the city of Yonkers, New York, its name).

Then they visit with Koen Kleijn, art historian and editor-in-chief of history magazine Ons Amsterdam, who takes them on a journey through Amsterdam's history -- from the innovative story of its canals to the disaster known as Tulipmania, the 1630 speculative mania that set the stage for generations of stock-market shenanigans.

PLUS: Tom sustains an injury --- from a bitterballen!
