History
Formed in 1787 from Addison County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Chittenden County was created from Addison County and named after Thomas Chittenden. In 1792, Franklin and Orleans were created from Chittenden's territory, and over the following decades, the county also contributed to the formation of Grand Isle, Washington, and Lamoille counties.
