Deposited records include a complete set of the printed volumes of the Primary Valuation of Tenements, 1848-64, also known as Griffith's Valuation, which lists householders and occupiers of land and buildings, together with details of lessors, acreages and rateable valuations. As a consequence again of the destruction of most pre-1901 census records, Griffith's Valuation is an important census substitute, and lists on average about 70 per cent of heads of families.  The annotated copies of Ordnance Survey maps associated with Griffith's Valuation have recently been transferred to the National Archives, where they are not yet available for inspection, but scanned copies can be viewed in the Valuation Office. Most but not all Valuation Office records and maps relating to the Six Counties have been deposited in the Public Record Office of Northern Ireland, where they are catalogued and available for inspection.

 

The Griffith's Valuation Survey is also held in the Irish Studies Library, Armagh County Museum and Armagh Ancestry.
