>From Keating's History of Ireland: "In the reign of his nephew Art, Cuchorb, king of Leinster, was reduced to great distresses by the Mamonians. He applies to Eochaidh, who was a powerful chief, for assistance, and he promises to Laighseach, his Dalta, a large reward, provided he seconded his applications. Through the persuasions of this preceptor, Eochaidh raised a large army—the Leabhar-Lecan says, no less than seven Cathas, or 21,000 men— Laighseach being also a MacFine, and himself a great warrior, attended the campaign. At Athtrodan, or Athy, the two armies engaged, and, after a bloody conflict, the Mamonians gave way— In crossing the Barrow they were again attacked by the Leinster troops, and here Eochaidh lost both a son and a grand-son. In Leix they sustained a third furious attack, and at Ossory they were entirely broke. Cuchorb, now reinstated in his dominions, generously rewarded his new allies. On Eochaidh, and on his posterity he settled the seven Fothortuaths, from a surname of this prince so called, in the county of Wexford. The third book of Lecan is minute in its account of the descendants of this Eochaidh—from him proceeded the O'Duns, O'Locheins, and O'Comains—the O'Dermods, O'Meathus, O'Luighneach, &c. &c. O'Nuallans were the chiefs of this stock for many generations."
