• Military: 1181; They plundered Fir-Lee and Hy-Tuirtre and took an immense prey of cattle.

Notes:

1175. The Kinel Enda were defeated and a great slaughter made of them by Eachmarcach O'Kane and Niall O'Gormley. (The territory of Enda was thirty quarterlands south of Inishowen. As already mentioned, the Gormleys were the leading sept of Clan Moen, and settled to the east and north-east of Strabane.)

1178. Randal, the son of Eachmarcach O'Kane, had been slain by the Kinel-Moen in the beginning of this summer. (Eachmarcach was the chief of the O'Cahans or O'Kanes at this period. Evidently the pact with Clan Moen was of a very temporary duration; this clan bordered on that section of Clan Connor Magh Ithe, known as the Clan Dermot, whose lands were north of theirs.)

The foregoing entries show the O'Cahans taking an active part in the tribal conflicts during the half-century or so which followed their expansion into the districts of Creeve and Cianachta. By the time of the last entry a new factor had entered Ulster history which was to exercise a continuing influence for two centuries on the area and clans in which we are particularly interested. This was the coming of the Normans.

1181. Eachmarcach O'Cahan already mentioned, with the men of Magh Ithe and the Clan Binny of the Valley (the latter evidently now Subordinate to the O'Cahans) mustered an army and crossed the Bann at Toome. They plundered all the territories of the Fir Li and Hy Tuirtre, and carried off many thousands of cows. At this point Fir Li as a state disappears from the Annals, and this is also the last appearance of the Clan Binny, who had first emerged in the Annals a century and a half previously. Cumee O'Flynn was killed by the Normans a few years afterwards, and Ui Tuirtre became a subordinate territory with an O'Flynn chief owning the Normans as overlords.

Eachmarcach married MacErc, Meardda. Meardda was born in 1123 in Ireland; died in DECEASED in Ireland. [Group Sheet] [Family Chart]

Notes:

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.
