Remnants of the village of Derstine (aka Derstein) are found along the Mill Creek and Old State Rd just south of Sellersville Borough. In 1730 the Derstein family purchased 200 acres in Rockhill and built a primitive mill on what became known as Derstein Mill Creek (a tributary of the Perkiomen). It was the first mill built between Centre Valley and Flourtown. They replaced it in 1742 with one that included the best machinery available at the time. Yet another replacement occurred in 1873. The family built a mansion near the mill in 1748.
Until 1940 Derstein was a stop on the North Pennsylvania Railroad.
