Griffith’s Valuation is a property tax survey carried out in the mid-1800’s under the supervision of Sir Richard Griffith. The survey involved the detailed valuation of every taxable piece of agricultural or built property on the island of Ireland and was published county-by-county between the years 1847 and 1864.
 

In addition, changes, or revisions, were recorded on an annual basis, directly into the books. Revision Books, Cancelled Books and Current Land Books recorded any changes to occupier, landlord, size of holding or value for each plot. So, if your ancestor sold a homestead years after the Primary Valuation was completed, the new owner's name would have been noted in the Current Land Book that covered that townland and that exact plot of land.
 

Cathy will show a case study of the use of records and information contained within the Griffith’s Valuations files in finding her McCarthy family in the Beara Peninsula of County Cork Ireland.
