  === Life Sketch ===
  Raghnaill (Ranall) was a son of Iomhar O'Cahan M1138.6 Raghnall, son of Imhar Ua Cathain, lord of the Craebh, Cianachta, and Fir- Li, fell through treachery and guile, by the Ui-Eoghain of the Valley.' Annals of the Four Masters, 1138
  
  The valley people are evidently Clan Binny, and the O'Cahan killed ushers the O'Cahan clan into a stormy future that occupies a large place in Ulster history for the next five and a half centuries. This is the first mention of the O'Cahans in the Annals, and it is perhaps appropriate that their coming was preceded by a great storm in the previous year. By 1138 they are obviously masters not only of the Creeve, but also of Cianachta and Fir-Li.
