Several Welsh families, associates in the invasion of Strongbow, settled in the West of Ireland. Of these, the principal, whose names have been preserved by the Irish antiquarians, were the Walshes, Joyces, Heils (_a quibus_ MacHale), Lawlesses, Tolmyns, Lynotts, and Barretts, which last draw their pedigree from Walynes, son of Guyndally, the _Ard Maor_, or High Steward of the Lordship of Camelot, and had their chief seats in the territory of the two Bacs, in the barony of Tirawley, and county of Mayo. _Clochan-na-n'all_, i. e. 'The Blind Men's Stepping-stones,' are still pointed out on the Duvowen river, about four miles north of Crossmolina, in the townland of Garranard; and _Tubber-na-Scorney_, or 'Scrags Well,' in the opposite townland of Carns, in the same barony. For a curious _terrier_ or applotment of the Mac William's revenue, as acquired under the circumstances stated in the legend preserved by Mac Firbis, see Dr. O'Donovan's highly-learned and interesting 'Genealogies, &c. of Hy. Fiachrach,' in the publications of the _Irish Archæological Society_--a great monument of antiquarian and topographical erudition. Page 90, line 6. 'William Conquer' was William Fitzadelm De Burgh, the Conqueror of Connaught. Page 91, line 4. Sir Samuel Ferguson introduces the poem as follows:-- Aideen, daughter of Angus of Ben-Edar (now the Hill of Howth), died of grief for the loss of her husband, Oscar, son of Ossian, who was slain at the battle of Gavra (_Gowra_, near Tara in Meath), A.D. 284. Oscar was entombed in the rath or earthen fortress that occupied part of the field of battle, the rest of the slain being cast in a pit outside. Aideen is said to have been buried on Howth, near the mansion of her father, and poetical tradition represents the Fenian heroes as present at her obsequies. The Cromlech in Howth Park has been supposed to be her sepulchre. It stands under the summits from which the poet Atharne is said to have launched his invectives against the people of Leinster, until, by the blighting effect of his satires, they were compelled to make him atonement for the death of his son. Page 99. 'There was then no man in the host of Ulster that could be found who would put the sons of Usnach to death, so loved were they of the people and nobles. But in the house of Conor was one called Mainé Rough Hand, son of the king of Lochlen, and Naesi had slain his father and two brothers, and he undertook to be their executioners. So the sons of Usnach were then slain, and the men of Ulster, when they beheld their death, sent forth their heavy shouts of sorrow and lamentation. Then Deirdre fell down beside their bodies wailing and weeping, and she tore her hair and garments and bestowed kisses on their lifeless lips and bitterly bemoaned them. And a grave was opened for them, and Deirdre, standing by it, with her hair dishevelled and shedding tears abundantly, chanted their funeral song.' (_Hibernian Nights' Entertainment_.)
