Although 1929 is way after Griffith's Valuation (which ranged from 1848--1864), this excellent book about the earlier valuations may prove helpful: "Richard Griffith and His Valuations of Ireland" by James Reilly. It is available from several genealogy and Irish interest bookstores on the internet. (Try a Google search.) I highly recommend it. I'm at work right now, but I'll check when i get home and see if any of those abbreviations the lister asked about are explained, and get back to you on it. Janet C-S
