A grandson of Tuathal's, the famous Conn Cetchathach (" the hundred-fighter "), whose death is placed in the year 177 after a reign of about twenty years, was constantly at war with the Munster ruler Eogan Mor, also called Mog Nuadat, of the race of Eber Find.
Mog Nuadat had a son Ailill Aulom who plays a prominent part in the Irish sagas and genealogies, and his sons Eogan, Cian and Cormac Cas, all became the ancestors of wellknown families.
The legendary account attributes the subjugation of the various peoples inhabiting Munster to Mog Nuadat, and the pedigrees are invariably traced up to ` his son Ailill Aulom.
