Le Roy is located at 40°20′50″N 88°45′44″W (40.347168, -88.762293).According to the 2010 census, Le Roy has a total area of 2.336 square miles (6.05 km2), of which 2.32 square miles (6.01 km2) (or 99.32%) is land and 0.016 square miles (0.04 km2) (or 0.68%) is water.LeRoy was laid out on 28 November 1835 by Asahel Gridley (26 April 1810 – 25 January 1881) and Merritt L. Covell (30 January 1808 – 17 September 1847). The founders were Bloomington businessmen. They had served together in the Black Hawk War, Covell as a captain and Gridley as a lieutenant.
Because of their brief service both men were popularly called “General”. Both would later serve in the Illinois General Assembly, and Gridley would eventually become McLean County’s first millionaire.LeRoy was the first of eight towns to be laid out within the present boundaries of McLean County during the great Illinois town-founding boom which peaked in the summer of 1836. LeRoy was located on a low mound, on prairie land, where the Bloomington to Danville state road crossed the road from Shelbyville to Chicago. The chief problem confronting Gridley and Covell was a place called Munroe, which consisted of a single store run by John W. Baddeley (24 June 1794 – 19 February 1871).
