Civil Registration of Births, Marriages and Deaths for the whole population of Ireland, started in 1864, but it took five years for the system to be fully integrated and for the majority of BMD's to be registered correctly. The civil parish was an important administrative unit used for land and taxation purposes. Many Irish records used in genealogy are arranged by civil parish, such as the Tithe Applotments etc. When Civil Registration began only non-Catholic marriages were recorded starting April 1, 1845. It wasn't until January 1, 1864 that Catholics were expected to comply with the reporting requirements and from this date all marriages, births and deaths were recorded in earnest. The information you will find here is not complete and should not be seen as a definitive list of all Marriages in Ireland for the year 1872.
