History
Several years after Illinois became a state (which happened December 18, 1818), William Blanchard and three other men (Charles Sargeant, Theodore Sargeant, and David Barnes) crossed Fort Clark (located in Peoria) to the eastern side of the Illinois River. The land here was a swampy floodplain; nevertheless, they made their claim on the land and built huts, growing corn and tomatoes in the fertile soil.
