Thirty minutes away by train from Amsterdam is the town of Leiden. Leiden is where the Pilgrims settled from 1608 to 1620. There is even a museum there for the Pilgrims. It is in the oldest house in Leiden which dates from the 1300s.
The museum is not much in and of itself, but the curator is a font of knowledge on the Pilgrims. It was great to discuss the Pilgrims with him. He even showed me the marriage license of my ancestor George Morton from 1612.
In addition to George Morton and his wife, I also descend from Kenelm Winslow, brother of Edward, a Leiden resident. Leiden is a charming town and I very much enjoyed wandering around its street. By the way, we do know that William Brewster stood in the room above from records. Otherwise, you just have to be content knowing your ancestors wandered the same streets 400 years ago.
