The Census of Ireland prior to 1901 has been lost, and in its absence Griffiths Valuation provides a valuable genealogical source to help fill the void. The Valuation was undertaken as a type of tax audit, and it recorded who the occupiers of property were (only the head of the household), how much property they occupied and, as a result, how much tax they were required to pay.
Tipperary Studies holds both hard and microfilm copies of the Tipperary returns, and the Valuation can be searched digitally on the Ask About Ireland website, www.askaboutireland.ie/griffith-valuation/
