Mission Statement

The purpose of the Slovenian Genealogy Society International, Inc. is to enrich the lives of individuals with Slovenian ancestry by helping them forge a link to their past.

SGSI is a self-help community whose common goal is to help members make use of available information to perform their own genealogy research.


We Do This By. . . 

  • Providing a forum to help individuals discover, research, and exchange genealogy information.
  • Preserving Slovenian genealogy records, publications, and oral histories in our dedicated Cleveland, Ohio office—the Macek Research Center.
  • Building a community where personal stories and experiences specific to the culture of Slovenia can be shared.

Displaced Persons Post World War II Indexing Project

After World War II, many Slovenes immigrated to the United States as displaced persons.  Many fled Slovenia after the war and were in residence in temporary displaced persons camps throughout Europe under the direction of the newly formed United Nations.  From these displaced persons camps, Slovenes sought asylum in various countries including the United States, Brazil, Argentina and Australia.

The United States 1948 Displaced Persons Act and the Refugee Relief Act of 1953 allowed a limited number of displaced persons to enter the United States meeting specific requirements.  Those seeking asylum and residence in the United States were assisted by agencies such as NCWC, USEP and Catholic Settlement Council in assembling the required paperwork, providing travel assistance, and finding a sponsor.     

St. Vitus Displaced Persons Cards Database of Displaced Persons and their Sponsors

In 2023, a collection of 2,222 index cards were found at St. Vitus Catholic Church in Cleveland, Ohio that contains information of displaced persons seeking entry to the United States and information of the sponsors of these displaced persons.  This project is organized by Thomas Kastelic and Denise Modic Urban.
