Irish Prison records are a key source for tracing family history because they record such a huge volume of prisoners, their relatives and in many cases their victims. This dataset is compiled from the collection housed in the National Archives of Ireland and covers most surviving records for prisons in the 26 counties of the Republic of Ireland. In total there are 2.7 million records, with information on over 3.5 million people. Please note that the database can only be used within the State Library building.
