The Hoaglands (Hooglandts) came to New Netherland in the early to mid 1600s, along with the rest of the settlers of this Dutch colony. As so often happened, their children or grandchildren preferred to settled in the wilderness rather than the established colony, which is how Jan & Jacobe Hoagland came to Hunterdon County.
The Opdycke family emigrated to America from Holland in the 17th century, settling at Gravesend in Kings County, New York. They certainly prospered in their new home and multiplied extensively. Consequently, there are many many Opdycke descendants, and also an extensive published genealogy. Because it is such a large family, I have not been able to research it as thoroughly as some others.
The Thatcher Family was prominent in both Amwell and Kingwood Townships in the 18th century. They were also very prolific! They keep showing up in other family trees, so published the Thatchers is really way overdue. And you will see that this tree just goes on and on!
As is my usual practice, children of daughters are listed but not grandchildren. Surnames of spouses whose family trees have been published here are highlighted in green. Any additions or corrections are welcome, either in the comments section below or by email.
