Description:
Griffith's Primary Valuation took place throughout Ireland during the middle of the 19th Century and the valuation of Clare was published in 1855. Those parts of Clare contained in the Union of Limerick were published in 1852. It was a survey of land occupation to determine the amount of tax a landowner or occupier should pay towards the support of the Poor Law System.
