The Hy-Fiachrach-Finn.—These were the branch of the Hy-Many seated in the territory of Moenmoy, mentioned in note 159. Their chiefs were the O'Naghtens and O'Mullallys, or Lallys. They deduce their tribe name from their ancestor Fiachra Finn, the son of Breasal, who was the son of Maine Mor, the common ancestor of all the Hy-Many, as we learn from their pedigree in the Book of Lecan, fol. 90 (vide supra, pp. 32, 33), in Mac Firbis's Genealogical Book, p. 328, and O'Flaherty's Ogygia, Part III. c. 76, where we read, Manii filius Bressalius quinque natos generavit, Fiachrium Fionn, ex quo O'Naghen, Dallanum, Conallum, Crimthannum, et Manium, a quo Hy-Maine Brengar.'
