To start your family research, first gather as much family history information as possible. Speak to relatives and list as much information as you can regarding birth dates, places of birth, maiden names etc.
As a next step visit Public Record Office of Northern Ireland (PRONI) which makes Northern Ireland’s unique archival heritage accessible to visitors. Visit their new state of the art building in Belfast’s Titanic Quarter, where you can search online archives and browse information leaflets. If you are unable to visit in person, you can still make use of the PRONI eCatalogue - guides, indexes and databases available online at www.proni.gov.uk.
Look at other genealogical websites - the 1901 and 1911 Census for Ireland at www.nationalarchives.ie and Griffith’s Valuation, a record of householders from c. 1860 www.askaboutireland.ie for useful free information. Alternatively check out www.rootsireland.ie for another great starting point.
