Collinsville IL 62234
The best recollection as to when Collinsville Township was established was in 1772. The mighty Mississippi River overflowed and the American Bottoms were flooded from the bluffs of Illinois to the banks of Missouri, causing many settlers to seek refuge on the bluffs. That is when Collinsville Township was established.
