The Illinois State Genealogical Society (ISGS) was formed in 1968 through the cooperative effort and forward thinking of Illinois genealogical society representatives, who envisioned a statewide genealogical organization. ISGS is a not-for-profit, nonsectarian, educational organization, with members from Illinois and worldwide. ISGS supports local Associate Member societies throughout the state, and has a unique partnership with the Illinois State Archives. ISGS promotes genealogical education and our motto is, "Honoring Illinois Ancestors."
