Irish Genealogy

Marie E. DalyMelanie McComb


The beginning steps are the same for all family historians: start with the known and move toward researching the unknown. It is important to keep a wide focus when researching all ancestors, but especially Irish ones, since Irish surnames can be very common. You trace back to your immigrant ancestor, and then try to determine his or her origin in Ireland. A good place to learn about researching Irish records is with one of the general guides listed below.

Many people believe that researching Irish ancestors is impossible because of the destruction of the Public Record Office (PRO) 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. This subject guide aims to provide you with a list of key resources, records, and repositories to assist in your Irish research.

Sources for identifying Irish place of origin: cemetery/burial records, church records, immigration records, military records, naturalization records, vital records.
