Looking at Google Maps, this looks to be quite a migration for what I think of 17th century travel. Can you shed any light on what would have motivated moving from Buitenpost to Harlingen, then to Breukelen? What were the economics like at the time? Harlingen, I assume, would have been a seaport at the time. I'd bet there were jobs to be found there. Because Buitenpost was inland, was it a farming village? Does a trip to Breukelen get Douwe closer to the seaports that would have left for the New World?
