Tigernan, son of Ualgarc Ua Ruairc, namely, king of Breifni, died this year: to wit, a man who defended his territory against the neighbours and was best of hospitality and prowess and charity that was in his time. And he was buried in the monastery of Sligech.
Brian the Freckled, son of Aedh, son of Feidhlimidh Ua Conchobuir, namely, one who was to be king of Connacht—the son of a king that never refused a person respecting what was due, or respecting a donative—died in his own stronghold.

Great forays were made by the Foreigners of Meath on Aedh, son of Art Mag Aenghusa. An attack was made by Mag Aenghusa and by Mac-Ui-Neill-buidhe on the track of the Foreigners and of those preys. And it is not easy to tell or to count the amount that was taken and that was slain of the Foreigners on that pursuit. And
Caislen-na-mallacht was built by William Ua Cellaigh this year opposite the great castle of Ros-Comain, to aid in taking the latter. A large host was led by the sons of Domnall, son of Muircertach Ua Concobuir and by all the lower part of Connacht to put provision into the great castle of Ros-Comain and they put a store into it in despite of what was against them. And they made an encampment around the Small Castle, but could not do anything more to it on that occasion.

And his wife, namely, the daughter of Mag Raghnaill, that is, Finnguala was of the party. And she came safe by virtue of her swimming.
