The community in southern Warren Township was originally known as Warrenton. In 1873, the Milwaukee & St. Paul Railroad (Predecessor to the Milwaukee Road) built a railroad depot in Warrenton, and the following year, Warrenton School was organized. In the early 20th century, entrepreneur Thomas E. Wilson purchased 2,000 acres of land in the area, which became known as the Edellyn Farms estate. The depot, post office and school were eventually renamed Wilson in his honor. After World War II, Wilson's identity slowly began to disappear. In 1954, Wilson School was sold for use as a private residence. It was eventually razed to make room for the expansion of Belvidere Road. In 1959, the Milwaukee Road Depot was abandoned and eventually razed. The nearby communities of Gurnee, Illinois and Waukegan, Illinois expanded, incorporating large parts of Wilson into their borders. In 1958, other parts of the area were incorporated into Park City, Illinois to avoid annexation by Waukegan. In 1968, several hundred acres of Edellyn Farms were sold to the city of Waukegan for development as the (now defunct) Lakehurst Mall. Today, very little of the Wilson area remains unincorporated, though the name still appears on topographic maps.
