About IGSI


The Irish Genealogical Society International (IGSI) is a volunteer organization dedicated to helping people discover their Irish heritage and ancestry. Founded in 1985, today our nearly 600 members are found worldwide.

IGSI is a nonprofit tax-exempt 501(c)(3) organization, incorporated in the state of Minnesota. The IGSI office and Irish research collection are located in the William J. Hoffman Library and Research Center located at 1185 Concord St. N., Suite 218 in South St. Paul, Minnesota.

Since IGSI is an all-volunteer organization with no office phone or staff, the preferred way of contacting us is by email to the appropriate contact.  Please be patient if you don’t get an answer immediately. Our volunteer staff have families and occupations that claim attention; we do our best to take care of Society business in a timely manner.

IGSI’s mission of genealogical research and education is evident in the programs and activities of the Society: online resources and print research materials, publications, educational assistance and library, web presence, and a biennial international conference.

The IGSI Library collection includes more than 3000 books, maps, and periodicals of interest and use to Irish family history researchers. Irish researchers have access to other materials within the William J Hoffman Library, including databases such as Findmypast and Ancestry.

IGSI publications include the quarterly journal, The Septs, a leading provider of information about Irish genealogical methods and sources and the bi-monthly eNewsletter, Ginealas. In addition to this website, IGSI volunteers set an online presence via the blog, Facebook and Twitter.

Monthly lectures [classes] on the second Saturday of the month (Irish Saturday) provide information on specialized sources and resources. An educational collaboration is the biennial Celtic Connections Conference.  IGSI and TIARA bring together leading experts from Ireland, Scotland, Canada and the United States to present the latest information about Irish genealogical research.

IGSI research volunteers offer assistance to new researchers, including one-on-one help on Irish Saturdays. Volunteers also work on commissioned Irish research projects.

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