Egneghan O'Donnell The first O'Donnell Chief of note. Clan was known as Clann Dalaigh, from Dalach, an early ancestor. The surname was derived from Dalach's 10th century decendant, Domhnall (Donnell). Their decent is traced from Niall Naoighiallach, of the nine hostages, King of Ireland at the beginning of the 5th century. From the beginning of the thirteenth century, wrested the promontory of Inishowen from the O'Cannanains, later extending their sway over Inishowen, Fermanagh, part of Cavan and the northern part of Connaught (Connacht). 1200 Egnehan O'Donnell, Lord of Tirconnell, sailed with the fleet of Tirconnell (13 vessels) by sea, and despatched his army by land, and pitched his camp at Gaeth-an-Chairrgin (inlet of Carrigin, a village 3 miles to the south of the city of Londonderry, on the west side of the River Foyle). Gerrmaide O'Boylan was slain by Egneghan. A battle was fought between O'Donnell on one side, and Ualgarg O'Rourke and Conor-na-Glaisfene O'Rourke on the other. The Hy-Briuin (O'Rourkes) were defeated, and their men dreadfully cut off, both by drowning and killing. Coner himself was drowned on this occasion. The battle was fought at Leckymuldory (O'Muldory's flag-stone, or flat surfaced rock, under the cataract at Bellice, now Belleek, on the River Erne, about 2 miles to the east of Ballyshannon). AFM 1201 Ualgarg O'Rourke mustered an army, and marched into Tirconnell. On their arrival in the country, they seized upon a number of cows and other property. Egneghan overtook them at Leck-I-Muldory, where a battl was fought between them, in which the Hy-Briuin (O'Rourke's) and their army was defeated and cut off with terrible havoc, both by killing and drowning. It was on this occasion that Coner na-Glais-fene (O'Rourke) was drowned. AFM On the same day, the Kinel-Owen made another predatory incursion into Tirconnell; and a conflict took place between them and O'Donnell, in which the Kinel-Owen were defeated, and Gerrmaidi O'Boylan and many others of the Kinel-Owen were slain along with him. AFM 1206 Egneghan took a prey, and killed some persons in Tyrone. AFM Egneghan plundered Hy-Farannan and Clann-Dermot (of the Kinel-Owen race); he took many cows and killed persons. He was overtaken by the Hy-Dermot, the O'Farannans and the O'Gormleys; and a struggle ensued, in which many were killed and drowned on both sides; but the Kinel-Connell ultimately bore off the prey, after much labour. The O'Donnells afterwards drove the Kinel-Owen out of the Plain of Magh Ithe, and established families of the Kinel-Connell in their place. AFI 1207 Egneghan set out upon a predatory incursion into Fermanagh, and seized upon cows; but a considerable muster of men of Fermanagh persued him and slew O'Donnell. Lord of Tirconnell, tower of the warlike prowess and hospitality of the province of his time; and some others of his nobility were slain along with him. AFM
