It is necessary to identify the top of this tree because there are other Williamson trees. One of those other trees (not yet published) is the William Williamson & Gattelyntje Gulick tree, Gattelyntje being the sister of Grietje. Their parents were Willem Williamson & Mayken Wyckoff.

Although previous generations of Williamsons are known, the family of Cornelius Williamson and Grietje Gulick is the first generation to appear in Hunterdon County. Grietje Gulick was the daughter of Joachem Gulick and Jakementie Van Pelt of Somerset County, NJ. Cornelius Williamson was the son of Willem Williamson and Mayken Pieterse Wyckoff of Gravesend, NY. Most of his siblings did not settle in Hunterdon except for his brother Nicholas Williamson. However, the only child of Nicholas that had a family I am aware of is daughter Maria (c.1736-1798) who married Hendrick Gulick in 1754. And since I know so little about this family, I am leaving them off this tree. Another branch of the family to settle in Hunterdon was headed by Peter Williamson and Catherine Broach. That also is a family I have not thoroughly researched.

The family I have focused on in the past is that of 2d generation William Williamson and Patience Hull. You will find their story in “Pine Hill Cemetery” and “Pine Hill Cemetery Revisited.”

As with all other family trees, I am including the children of daughters but not their grandchildren. Surnames of in-laws who have trees published on this website are highlighted in green. Additions and corrections are always welcome, either in comments below or by email.
