Censuses and lists before Twentieth Century Ireland

Pender’s Census of 1659

Almost all Gaelic manuscripts and all Catholic records were destroyed by the Gall (foreigners) from the Norman invasion of Ireland in 1169 until 1782 and the liberal period of Grattan's Parliament.

There are only a few sources of population records before then and no real surviving census until 1901. The National Archives of Ireland has all available records.
