In 1788, Massachusetts abandoned its claim to this region in favor of New York. Oliver Phelps and Nathaniel Gorham of Connecticut settled with the state of Massachusetts for a title of land in western New York. On July 8, 1788, Oliver and Nathaniel met with the Senecas and signed the Treaty of Buffalo Creek at Geneseo in Livingston County where the Indians gave up their title. The District of Northfield was formed in Ontario County in 1792. This became the Town of Northfield in 1796. What is now the Village of Pittsford was settled the same year. As Northfield was subdivided in the following years, a final split formed the towns of Pittsford and Henrietta in 1814.
