The first white settler in what became Farmington Township was a Quaker from Farmington, New York, named Arthur Power. He purchased land in 1823 and returned in 1824 with a group of families and associates to clear the land. The settlement became known as Quakertown. A post office was established in February 1826 with the name of Farmington. The original post office is still standing today, and is a designated historical site. The township of Farmington was organized in 1827, and the settlement was incorporated as the village of Farmington in the winter of 1866–67. A fire on October 9, 1872 destroyed many buildings in the village center. Farmington was incorporated as a city in 1926.
