The Primary Valuation (also known as Griffith’s Valuation) was published between 1847 and 1864. There is a printed valuation book for each barony or poor law union in the country showing the names of occupiers of land and buildings, the names of persons from whom these were leased and the amount and value of the property held. – Fáilte Romhat
