The original village site was established in Missouri, near what was called the Harry Turnstall spring, now known as “Old Town.” Despite homesteading efforts by early settlers in the region, the spring was divided into multiple plots. It wasn't until the arrival of the Frisco Railroad in 1883, which extended its track from Springfield, Missouri, to Memphis, Tennessee, and established a station and depot between the spring and the Spring River, that the town shifted to the Arkansas side of the river.
