Phosphate was discovered near Hawthorne during the late 1870s. Near the same time, the first subdivision, the Town of Hawthorn, was platted. The area had been previously known as Jamestown—named after James M. Hawthorn. A second subdivision, Waits Crossing, was platted in 1881. The subdivisions provided north–south and east–west rights-of-way, which brought rail service. Track was first laid by the Peninsula Railroad in Hawthorne in 1879 for a north–south line intended to connect Waldo and Ocala. Near the same time, track laid by the Florida Southern Railroad reached Hawthorne; its east–west line was intended to connect Palatka and Gainesville. Each railroad company had a depot in the Hawthorne area, about a half-mile apart. A Hawthorn post office was established in 1880, and its spelling was changed to Hawthorne in 1950.
