In 1196, the Annals of the Four Masters record the death of a son O'Faelain (Phelan), of the Desies who was part of a failed expedition into Ulster. It appears that this son of O'Faelain was part of a coalition including Rory Mac Donslevy, the English, and chieftains of Connaught. They marched their army against the Kinel-Owen and Oriors. The Kinel-Owen and the men of Orior gave them battle on a plain in Armagh where Mac Donslevy was defeated with dreadful slaughter with twelve of the sons of the lords and chieftains of Connaught slain, along with many of an inferior grade also slain including the son of O'Faelain of the Desies.
