History

Formed in 1781 from Cumberland County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Windsor County was created from the extinct Cumberland County and named after the town of Windsor. In 1781, Vermont briefly attempted to annex part of New Hampshire into Windsor County, but gave up the attempt in 1782, and the overlap with New Hampshire counties ended. Between 1783 and 1806, Windsor County gained several towns from Rutland County, including Bethel, Rochester, Stockbridge, and Benton's Gore. In 1792, Windsor County lost the town of Mount Holly to Rutland County when that town was created.
