He could only get at parts of it through O'Donovan's TRIBES AND CUSTOMS OF HY MANY and TRIBES AND CUSTOMS OF HY FIACHRACH. After waiting for 350 years, Mac Fhirbhisigh's great work was finally published by De BĂșrca Books in 2003. So, when Woulfe and MacLysaght disagree on a family origin, I go to Mac Fhirbhisigh to see who's right. The MacFirbis genealogies have been online for quite a while. Un-translated of course with a weak index at the end. Not for the faint of heart. _http://clanmaclochlainn.com/macfirb.htm_ (http://clanmaclochlainn.com/macfirb.htm) I read a story once that said that MacLysaght had a copy of O'Hart's Irish pedigrees open on his desk at all times. I don't know if that's true or not. It was not comforting to hear. John
