HistoryA character grade: shown, never part of Caseyville Township’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Caseyville Township’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±1.1 points) is firm at this size.

What stands out about Caseyville Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
A wealthy man named Charles Harbour built a house here, and in 1845 built a sawmill. There were deposits of coal in the area, and Harbour was one of several members of the Illinois Coal Company, along with Zadok Casey, Walter Seates, Malcomb Robinson, Charles Barrett and John Roy. Casey had held several offices including United States Representative and Lieutenant Governor of Illinois. In 1849, the Illinois Coal Company founded the town and named it for Casey. Coal mining began, and in 1851 the company constructed a railroad to nearby Brooklyn to transport the coal. In 1850 there were about 40 people here, and by 1851 this had increased to about 150; by 1881 the population was approximately 800. The first post office was established here in 1856, and the village was incorporated in May 1869. A school was built in 1872, and a church in 1879.
