The area post office was established by Isaac Everett in 1837 as "Everett's Creek"; in 1838, this was changed to "Crews Creek" (presumably after the presentCruises Creek that is south of the city); in 1839, Thomas Hordern renamed it "Bagby".[5]
In 1840,Kenton was formed fromCampbell andBoonecounties. Local farmer John McCollum donated a site at the center of the new county to be its seat of governance, and the name "Independence" was chosen to honor the liberation of locals from Campbell County.[5] The post office was renamed the same year. Quickly settled, Independence was formally incorporated by thestate assembly in 1842.[6][7]
Because the majority of the county's population resided along theOhio River, Independence was eventually obliged to share its status as county seat with the larger city ofCovington, a situation later repeated in Campbell County between the centrally locatedAlexandria and the larger, riversideNewport.
