History In 1830, Bailey Hobson, a Quaker, was the first settler in what would become DuPage County, Illinois, as well as Lisle Township. The town of Lisle was settled in 1832, by brothers James C. Hatch and Luther A. Hatch after the close of the Black Hawk War. The two brothers acquired land near what is now Ogden Avenue and began a small farming community named "DuPage" or "East DuPage" because, of its proximity to the east branch of the DuPage River.
