Jacksonville, one of Fountain County's early settlements, was established by John Bowman and his father Henry in the early 1830s on land situated just north of Mill Creek and was named for Andrew Jackson. The town's name in informal speech was often shortened to "Jackville". The first settler at the site was Richard Williams who erected a cabin as early as 1826, several years before the town was laid out, with the first house erected after Jacksonville's platting belonging to William Guilliams. By the 1880s, it contained about two dozen houses.
