Most of Vernon was built recently: 5% of its homes predate 1940 and the median home dates from 1981. Below: maps from 1950 on and the census since 1900.
The pioneer city was the site of a major Native American settlement before colonization. In the 1820s, during the Florida Territory era, Vernon started off as a colonial settlement called "Roche's Bluff" after one of the earliest settler's surname, Stephen J. Roche, who built and owned a trading post along Holmes Creek. The community was renamed "Vernon" in 1851. It was renamed for George Washington's Virginia home, Mount Vernon, playing off the county's name being Washington County. Vernon held the county seat from 1851 until 1927, when the seat was moved to Chipley.
