Catlettsburg's history begins in the decades directly following the American Revolution, as many frontiersmen passed through the area on their western trek along the Ohio River. Alexander Catlett, the first landowner of the area, came to the site in 1798. His son, Horatio Catlett, opened a post office on December 5, 1810, with himself being the postmaster. This was the first known use of the name Catlettsburg being used officially as it had been previously known as Mouth of Sandy. In 1849, James Wilson Fry, a landowner who purchased the site from the Catlett family in 1833, sold off town lots of what was soon to be the town of Catlettsburg. (The Kentucky Encyclopedia says the Catletts settled the area in 1798.) and Catletts resided at the location until 1847.
