The German Palatines arrived about 1710 and were also referred to as Dutch. The German language had become prevalent, but the original name was preserved for the Mohawk Dutch.
If you're looking for ancestors during this period, there are a few things to keep in mind. First of all, most of the early Dutch were men who married Native Americans. Land ownership was not legal until the West India Company was formed in 1621. Even then, those early Dutch often had no fixed address. They were primarily fishermen.
While you won't find a census taker making the rounds during those days—even if they could have tracked down these nomadic fishermen, some of the early names have survived. Among these early settlers were families with the names Flanders, Wiles, Chawgo, Clock, Cool, Swartwout, Wendell, Sanders, and Snell.
When families did begin to form and settle down, there was another issue. A marriage was considered a civil contract among the Mohawk Dutch. A marriage was recognized by the community when a man and wife began living together. Local ministers were rare and a religious ceremony often did not take place for months, when a visiting minister happened by.
The result creates a question as to when a couple was officially married. The answer would vary according to which you choose to use as the marriage date: the civil contract or the religious ceremony. It would not be unlike getting married by the Justice of the Peace and then having a wedding, with all the trimmings, at a later date.
These are just a few things to keep in mind when researching the Mohawk Dutch. Later, when they migrated farther West, they carried the Mohawk Dutch name with them. You'll find local histories across the country listing immigrants' ancestry as Mohawk Dutch. A good source for more information about Mohawk Dutch, is the Three Rivers web site.
