As settlers began to move West, families such as the Rutledges, Funks, Passwaters, Bishops, Nobles, Wakefields, and Martens settled in the immediate vicinity of the present village of Heyworth as early as 1824. Campbell Wakefield was the primary founder of Heyworth. In the course of his achievements, Wakefield became the owner of a vast tract of land including what is now Heyworth. He continually added to his original tract until he obtained about in one plot.

As the population of the region increased and industries began to spring up, railroads were becoming a great advantage. In 1852 and 1853, the Illinois Central Railroad was constructed through the Wakefield land. When the line became operational in 1855, the residents hoped to put a train station in the vicinity. Many property owners vied for the station, but Wakefield immediately donated a large tract of land for the station. Additionally he set aside adjacent land for the foundation of a town, a Presbyterian church, and a district school.

The first post office was built in the vicinity under the name Short's Point in 1847 before a subsequent renaming to Independence in 1850. In 1856, when the new railway station was opened, the name "Elmwood" was chosen, but it was soon discovered that this name was already taken by a locality in Peoria County. The president of the Illinois Central Railroad proposed calling the new station "Heyworth", after Lawrence Heyworth, an English director of the railroad, which became official on March 29, 1858.

After the establishment of the station, Campbell Wakefield made several donations to encourage trade and induce businessmen to locate in the new town. He became the proprietor of the new town, and the village of Heyworth was incorporated on March 31, 1869.
