Welcome to the Jefferson County Historical Society

The Jefferson County Historical Society, founded in 1886, is the primary organization in Jefferson County, New York that collects artifacts, books, and documents that reflect the entire history of the county, including every geographical area and every chronological period. We preserve the history that makes Jefferson County a special place to live, work, and visit. Originally housed in the Flower Memorial Library, today the Society is located in the beautiful 19th century Paddock Mansion.
