National Archives of Ireland

The National Archives of Ireland have digitised the household returns and ancillary records for the censuses of Ireland of 1901 and 1911, which are in the custody of the National Archives of Ireland and represent an extremely valuable part of the Irish national heritage.
All thirty-two counties for 1901 and 1911, are now available. Corrections and improvements will be ongoing. A small amount of material is still missing, and will be placed online as soon as possible.
