“The Composition Act (1823) specified that tithes due to the Established Church, the Church of Ireland, which had hitherto been payable in kind, should now be paid in money. As a result, it was necessary to carry out a valuation of the entire country, civil parish by civil parish, to determine how much would be payable by each landholder.” – National Archives of Ireland
