* New York: Originally founded by the Dutch as New Netherland, New York was captured by the English in 1664. A significant Dutch population remained, and their influence is evident in the city's architecture, street names, and cultural traditions.
* New Jersey: Like New York, New Jersey was also part of New Netherland. Although the English took control, a sizable Dutch population remained, particularly in areas like Bergen County and the Raritan Valley.
It's worth noting that there were also smaller Dutch populations in other colonies like Pennsylvania and Delaware, but the two mentioned above had the largest Dutch-speaking communities.
