History
Samuel W. Allerton was a wealthy landowner in Vermilion County who had made his fortune on the agricultural and livestock markets. He was one of the founders of the First National Bank of Chicago and Co-founder of the Chicago Union Stockyards. The town was founded on a  tract of land in the southwestern part of the county which Allerton purchased in 1880. It had formerly been known as Twin Grove Farm (because of two very similar  groves of trees in the area). When the C&EI railroad came through the area, he gave them a right-of-way through his land, and then established a grain elevator and platted the village; later he provided land for a park, established a bank, provided funds for a new brick school in 1894, and installed a water system. Allerton himself continued to live in Chicago.

Samuel's total land holdings included 78,000 acres across four Midwest states.
