the book you are probably refering to is "The Ancient and Royal Family of O'NEILL" by Desmond O'NEILL of Eire (Ireland). Very well written. I am searching my family of O'NEILL's from county Maigh Eo (mayo) and have found family members on it myself. There is also a cd-rom version of the book that is also available. Check out: Desmond O'Neill, One Shore Road, Meath, Co. Louth, Ireland. telephone: 353-42-75346 fax: 353-1-6718470 lamh dhearg abu, sean o'neill, nua eabhrach
