Welcome to St. Clair County, located in Southwestern Illinois across the Mississippi River from St. Louis. Established in 1790, it is Illinois’ oldest county. We gratefully acknowledge the efforts of SCCGS volunteers who preserve and publish extensive information about our American, French, German, Irish, and eastern European ancestors’ sojourn here. Join our free events.
