Tryon County was a county in the colonial Province of New York in the British American colonies. It was created from Albany County on March 24, 1772, and was named for William Tryon, the last provincial governor of New York.[1] The county's boundaries extended much further than any current county. Its eastern boundary with the also-new Charlotte County ran "from the Mohawk River to the Canada line, at a point near the old village of St. Regis and passing south to the Mohawk between Schenectady and Albany." It extended north to the St. Lawrence River; its western boundary was the Treaty of Fort Stanwix's Line of Property, following the Unadilla River, Oneida Lake, Onondaga River and Oswego River to Lake Ontario, as the Iroquois Confederacy still controlled locations further west in the Indian Reserve. Tryon County's seat was Johnstown, which is today the county seat of Fulton County.[2] The Tryon County Courthouse, built in 1772–1773, was listed on the National Register of Historic Places in 1972.[3] The Tryon County Jail, also built in 1772–1773, was listed on the National Register of Historic Places in 1981.[3]
The county was divided into five districts: Mohawk, Palatine, Canajohorie, German Flatts, and Kingsland. The county court house and jail were erected in Johnstown in 1772 establishing Johnstown as the county seat. Three of the seven original judges were relatives of Sir William Johnson: Sir John Johnson (son), Guy Johnson (nephew), and Daniel Claus (son-in-law) with a fourth judge being close business associate and neighbour, Colonel John Butler. The remainder of the original seven judges were Peter Conyne, Jelles Fonda and John Wells. Guy Johnson, John Johnson, Daniel Claus and John Butler sided with Britain during the American Revolution while Fonda, Wells and Conyne supported the American cause.
Its members in the Province of New York assembly were Sir John Johnson and Hendrick Frey.
