The Jewish Genealogical Society of Illinois (JGSI) is a non-profit, volunteer-driven organization established in 1981 and now with over 300 members. JGSI is a member of IAJGS, the International Association of Jewish Genealogical Societies.

We help members collect, preserve, and perpetuate the records and history of their ancestors and serve as a resource for the worldwide community to research their Chicago area Jewish roots. JGSI hosts our monthly meetings with informative speakers and expert genealogy volunteers to answer your questions about Jewish genealogy.
