History
The earliest settlers of the area were the Delaware Native Americans, who had a path through the woods from Lambertville through Mount Airy, Ringoes and Reaville to Newark which would later become the route followed by the Old York Road.
In 1935, local farmers signed a declaration against the Potato Control Law, which established federal controls on the growth of the crop, stating "[t]hat we protest against and declare that we will not be bound by the 'Potato Control Law,' an unconstitutional measure recently enacted by the United States Congress. We shall produce on our own land such potatoes as we may wish to produce and will dispose of them in such manner as we may deem proper."
