Groton was in the former Central New York Military Tract. The town was formed in 1817, before the formation of Tompkins County, from the Town of Locke as the "Town of Division." Many of the early residents from New England elected to change the name to "Groton." In 1888, the community of Groton separated from the town by incorporating as a village. Groton was also home to the original Corona Typewriter Company which later merged to form Smith Corona.
