Gilbertsville is a census-designated place (CDP) in northwest Montgomery County, Pennsylvania, United States. The population was 4,832 at the2010 census,.
Gilbertsville began when the descendants of William Gilbert, an English astronomer, physician, and physicist, decided to permanently move to America. Although many of the Gilberts fought for America in the Revolutionary War, Abijah Gilbert did not relocate his family until 1790. In the fall of 1789, 1,000 acres (4.0 km2) of land were purchased for the modern-day price of $2000. It was the first land purchased from the Morris Trust inMontgomery County, Pennsylvania. The Gilberts purchased more land in later years. A Gilbert Family letter recalls that as Abijah Gilbert's son, Joseph Thomas Gilbert, was disembarking in Philadelphia, George Washington patted him on the head and said, "A fine, rosy-cheeked English boy, who will make a good American Citizen."The name Gilbertsville derived from the large number of Gilbert family, descended from Hans George Gilbert who relocated from Hoffenheim, Germany in 1750. He and his sons Bernhard and Johan George Gilbert are buried in the New Hanover Evangelical Lutheran Churchyard. The village was originally a part of McCall's Manor.
