If you are a Knickerbocker then some of your earliest ancestors to the new world were Dutch and lived here in North America in a place that was then called New Netherlands. The first Knickerbocker, Harmon Knickerbocker ( there was no such surname until he started using it), and his wife Lysbet Bogaert were both immigrants from Holland.
A fantastic book about the times and places they lived is: The Island at the Center of the World: The Epic Story of Dutch Manhattan and the Forgotten Colony That Shaped America by Russell Shorto.
