the proprietor, Mac Rannall, who, however, succeeded in recapturing his stronghold. In 1223 William de Lacy, one of the great Anglo-Norman settlers in Ireland erected “the crannog of _Inis-Laodhachain_, and the Connacht men entered forcibly upon it, and let out on parole the people who were in it.” This erection of a lake-dwelling by a Norman baron is an instance of the habit laid to the charge of many of the English, of forsaking their own language and usages, and of living according to the manner of the Irish amongst whom they dwelt. “The names _Inis-Laodhachain_ and _Loch-Laodhachain_ are now obsolete.” In 1220 “Walter de Laci came to Erinn, and performed a great hosting to the crannog of O’Raighilligh.[176] He went upon it and obtained hostages and great power.” The crannog here referred to “appears to have been situated in Lough Oughter, county Cavan, where the old castle of Cloch-Uachtair (or Cloch-Oughter) now stands. In a letter from Guy de Chatillon to Henry III., dated July, 1224, Grennoch Oraely (as the name is therein written) is stated to have been captured from William de Lacy by Oraely, Walter de Riddelsford, and Richard Tuit, on the same day on which the castle of Kilmore (county Cavan) was taken, from which it appears to have been in the neighbourhood.” There is evidence that some crannogs were constructed by the Northmen, for in 1170 the chief of a small territory in the barony and county Monaghan “was killed by the men of a fleet which came from the Orkneys, in the island which had been constructed by themselves in _Loch-Ruidhe_, i. e. Inis-Lachain.” There is no lake in Ireland now known by that name; but to the south of Coleraine there is a small island in the river Bann called “the Loughan,” which bears all the appearance of having been artificially constructed.[177] In 1150 an Irish chief was killed “on the island of _Loch-Laighaire_.” This crannog lay in the country of the “_Sliocht O’Neills_,” and, as appears from subsequent references, was situated to the south of Lifford, in the barony of Clogher, county Tyrone, and was the residence of that branch of the O’Neills. It is written _Loch-Laoghaire_ and _Loch-Laighaire_, i. e. Leary’s Lake, said to have been so called from “Leary the Victorious,” one of the heroes of the Red Branch Knights of Ulster, in the first century; but for nearly two hundred years it has been generally known under the designation _Corcreevy_, i. e. wooded hill. In 1845, when the water had been drained off, the crannog was here discovered. There are several allusions to it in the Irish Annals. In 1325 “O’Donnell, the son of Brian O’Neill, Lord of Tyrone, died at Loch-Laighaire. In 1431 Nachtan O’Donnell went to assault the castle of Loch-Laighaire, and took it from Turlough O’Donnell, and all the spoils that were in it he carried off.” In 1436 the crannog had been seized by the O’Neills, when some of the same sept summoned Mac Guire to their
