Hello All, Following on from Paul's posting, there is an excellent book on the subject by James R Reilly. It's an American publication with the title, "Richard Griffith and His Valuation of Ireland." My copy is a reprint (2002) of the original in 2000. It was printed for the Clearfield Company Inc by Genealogical Publishing Co Inc out of Baltimore, Maryland. The book's size is A4 & contains about 108 pages with plenty of figures/diagrams for easy understanding. The ISBN is 0 8063 4954 9.
