Hi Kay, Yes, LDS microfilmed [most of] the same set, lucky us. That long geographic title is often abbreviated in articles, as "OKM" "OCM" "OK" or Casey. Helps the spelling resistant among us. Use Ray Marshall's article, describing contents of each volume, Mother Lode article IGSI <http://www.irishgenealogical.org/igsi_published/casey.htm> to figure out which volumes / films to order. Note: Some library catalogs have the different volumes catalogued separately, not always in a set, due to differences in the titles / publishing house / authors' names. One more opportunity for creative searching! Barb Glassel ______________________ Barbara, I believe Casey's work can be found on microfilm at your local Family History Center. Starting with film # 823801 Vol.1 thru 15. Is this the same work? "O'Kief, Coshe Mange, Slieve Lougher and Upper Blackwater" Kay
