Oakville, originally known as "Pleasant Hill," was laid out by John Holsinger in December 1873. The town was renamed Oakville around 1880 to avoid confusion with Pleasant Mills in Adams County. The development of Oakville was closely tied to the arrival of the Lake Erie and Western railroad in 1872. By 1880, Oakville had a store, a post office, and a growing community centered around the railway station.
