Addison is a northern Breckinridge county town near the Ohio River about eight miles northwest of Hardinsburg. A Holt post office opened at the site in 1880, probably named for Judge Joseph Holt or his family, and was renamed Addison in 1889, for the local postmaster. In 1889 a Holt post office was opened near the Holt home outside of town. It closed in 1958. The Addison post office closed in 1965.
West of Addison on KY 144 is the home of Judge Joseph Holt (1807-1894), who served as U.S. Postmaster General, Secretary of War, and the first Judge Advocate General, appointed by Abraham Lincoln in 1862. The circa 1850 Holt home is now owned by the Breckinridge County Fiscal Court and restoration efforts are being organized by the Friends of the Holt Home, Inc.
