Welcome To Our Website

The Genealogy Society of Southern Illinois (GSSI) was organized in Carterville, Illinois in March 1973, for the purpose of encouraging the study of family history and genealogy; helping others gather genealogical information; and preserving, protecting, and publishing information of importance to Southern Illinois genealogy. Our Constitution and a list of current Officers are posted on this website.

GSSI includes in its geographic area the twenty-eight counties of Illinois south of Interstate 70: Alexander, Clay, Clinton, Edwards, Franklin, Gallatin, Hamilton, Hardin, Jackson, Jefferson, Johnson, Lawrence, Marion, Massac, Monroe, Perry, Pope, Pulaski, Randolph, Richland, Saline, St. Clair, Union, Wabash, Washington, Wayne, White, and Williamson.IL28blue_medium

The GSSI Genealogy Collection at the John A. Logan College Library consists of more than 1000 books and several hundred reels of microfilm. The collection does not circulate, but it is catalogued and may be searched through the JALC Library website. Entering a title or keyword in the box marked "Search catalog for:" will produce returns from the SHARE database of  the Illinois Heartland Library System.  Since the system consists of hundreds of libraries in Central and Southern Illinois, the list of results may be very long. To narrow returns to  the GSSI Collection, scroll down the left hand column of the page to "Assigned Branch" and check on John A. Logan College Library.

The Society issues a Newsletter as needed and publishes a quarterly journal, The Saga of Southern Illinois, both of which are distributed to all members of the society. GSSI also has an extensive list of both book and on-line publications.


The Genealogy Society of Southern Illinois is open to everyone interested in genealogy, regardless of race, creed or religion. All memberships are for the calendar year. Join GSSI or renew your membership now.
