Griffith's Valuation for Diane
Griffith's Valuation is a record of taxes or tithes paid to the English government by each land owner or tenant. Many census records were destroyed in the 1800's so Griffith's Valuation is used to find ancestors in Ireland.
I haven't looked for Griffith's yet, but I imagine you could find it in the library. It might just give you a microfilm number.
