Charlotte County, Province of New York
Charlotte 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. The county was named for Charlotte, Princess Royal, oldest daughter and fourth child of George III of the United Kingdom. Its boundaries extended far further than any current county. Its western boundary 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." Its southern boundary was near present-day Saratoga Springs. Much of western Vermont, then claimed by New York, was also part of the county. Its northern border was also the Canada–US border. Its county seat was Fort Edward.
On April 2, 1784 the new state's legislature voted to change the name to Washington County, in honor of George Washington, stating, “From and after the passing of this act, the county of Tryon shall be called and known by the name of Montgomery, and the county of Charlotte by the name of Washington.” In 1799 Clinton County was created from part of Washington County. Clinton County itself was partitioned to form other upstate counties. The Town of Cambridge was transferred in 1791 from Albany County to Washington County.
