[4] In 1738, Johan Philip Kaes (Case), who had emigrated from German Palatinate to the Americas, purchased a 374-acre tract of land in western New Jersey from the sons of William Penn.

After Johan's death, the land was divided among his descendants, and his son Philip Case eventually acquired the portion that would become the Case-Dvoor farmstead.

In 1798, Johan's son Philip built a farmhouse, which was constructed in Georgian style by local mason William Connor.

The farmstead also includes a variety of outbuildings constructed in the 19th and 20th centuries, which provide an important record of the area's agricultural history.

Structures included in the National Register of Historic Places listing are the house, two barns, wagon house/garage, office, equipment shed, and well.
