The Fort Gay community traces back to 1789, when 11 people established a settlement at the junction of the Tug and Big Sandy rivers, across from what is now Louisa, Kentucky. In 1875, it was chartered as Cassville; though it was simultaneously known as Fort Gay. In 1932, the town's name was officially changed to Fort Gay. Although there is no evidence as to why the name was changed, there are several prevalent theories: that either the railroad company or post office did not want two Cassvilles on the same route/state (there is another Cassville, West Virginia), or that a Civil War nurse named Gay became synonymous with the town.
