How to Discover Your Irish Ancestry

Many people believe that researching Irish ancestors is impossible because of the destruction of the Public Record Office in 1922. While many records were destroyed, other sources, such as deeds and Catholic Church records, were never located in the PRO and still exist. A lot of genealogical material has come online in recent years, and the growing list of Internet options has resulted in many more people finding their ancestors in Ireland.

NEHGS experts know the best resources for Irish genealogy and can teach you to use them effectively. Use the guide below to browse a wide variety of Irish records, subject guides and books.
