About Us

Welcome to the Irish Genealogical Society International (IGSI).

We are dedicated to assisting our members and others in the discovery of their Irish ancestry. 

Founded over 35 years ago by a small group of people interested in sharing their knowledge, IGSI has since developed into a well-respected Irish genealogical society with over 600 members in six countries, and an extensive library and research facility. 


The Irish Genealogical Society International, Inc is a Federal IRS 501(c)3 non-profit corporation. 


We are located at: 1185 Concord Street North, Suite 218, South St Paul, MN 55075



IGSI is proud to be members of the Federation of Genealogical Societies, the Council of Irish Genealogical Organizations and the National Genealogical Society.
