Property records

Records of place can provide useful information about where your ancestors lived. The main sources for records of place are Griffith's Valuation, the Tithe Applotment Books, estate papers and maps.

Griffith's Valuation

The primary valuation of Ireland or Griffith's Valuation - carried out between 1848 and 1864 to determine liability to pay the Poor rate (for the support of the poor and destitute within each Poor Law Union) - provides detailed information on where people lived in mid-nineteenth century Ireland and the property they possessed.  Griffith's Valuation is fully searchable online, free of charge on the Ask About Ireland website.

Tithe Applotment Books

The Tithe Applotment Books were compiled between 1823 and 1838 as a survey of land in each civil parish to determine the payment of tithes (a religious tax). Unlike Griffith's Valuation they do not cover cities or towns. The Tithe Applotment Books are available online, free of charge on the National Archives of Ireland website.

Estate papers

In the eighteenth and nineteenth centuries, the vast majority of the Irish population lived as tenant farmers on estates. The administration of these estates produced large quantitles of records such as leases and deeds, rentals and account books, maps and correspondence. You can search our Catalogue and Sources database for records belonging to estates held by the NLI.


Maps can contain a wealth of information on the topography of a particular location as well as on landholdings of individual tenants. Many collections of estate papers contain detailed maps of parts of the estate. In addition the NLI holds a large collection of maps created by individual surveyors, such as the Longfield Map Collection. Search our Catalogue and Sources database to locate maps for a particular county or estate.
