We now come to Eochaidh [Yohee] Muigh-mheadhoin [Mwee-va-on] who was father of the celebrated Niall of the Nine Hostages. From one of his sons, Brian, come the Ui [Ee] Briain, that is, the collection of families composed of the seed of Brian--the O'Conors, kings of Connacht; the Mac Dermots, princes of Moylurg, afterwards of Coolavin; the O'Rorkes, princes of Breffny; the O'Reillys, O'Flaherties, and Mac Donaghs. From another son of his, Fiachrach, come the Ui Fiachrach, who were for ages the rivals of the Ui Briain in contesting the sovereignty of Connacht--the O'Shaughnesies were one of the principal families representing this sept.[24] Eochaidh Muigh-mheadhoin was succeeded in 366[25] by Crimhthan [Crivhan], who was one of those militant Scots at whose hands the unhappy Britons suffered so sorely. He "gained victories," say the annals, "and extended his sway over Alba, Britain, and Gaul," which probably means that he raided all three, and possibly made settlements in South-west Britain. He was poisoned by his sister in the hope that the sovereignty would fall to her favourite son Brian. In this, however, she was disappointed, and it is a noticeable fact in Irish history that none of the Ui Briain, or great Connacht families, ever sat upon the throne of Ireland, with the exception of Turlough O'Conor, third last king of Ireland, ancestor of the present O'Conor Don, and Roderick O'Conor, the last of all the High-kings of the island. Brian being set aside, Niall of the Nine Hostages ascended the throne in 379. It was he who first assisted the Dál Riada clans to gain supremacy over the Picts of Scotland. These Dál Riada were descended from a grandson, on the mother's side, of Conn of the Hundred Battles. There were two septs of these Dál Riada, one settled in Ulster and the other in Alba [Scotland]. It was from the conquests[26] achieved by the Scots [_i.e._ Milesians] of Ireland that Alba was called Lesser Scotia. In course of ages the inconvenient distinction of the countries into Lesser and Greater Scotia died away, but the name Scotia, or Scotland, without any qualifying adjective, clung to the lesser country to the frightful confusion of historians, while the greater remained known to foreigners as Erin, or Hibernia.[27] This Niall was surnamed "of the Nine Hostages," from his having extorted hostages from nine minor kings. He mercilessly plundered Britain and Gaul. The Picts and Irish Gaels combined had at one time penetrated as far as London and Kent, when Theodosius drove them back.[28] It was probably against Niall that Stilicho gained those successes so magniloquently eulogised by Claudian, "when the Scot moved all Ierne against us and the sea foamed under his hostile oars." Niall had eight sons, from whom the famous Ui [Ee] Neill are all descended. One branch of these, the branch descended from his son Owen, took the name of O'Neill in the eleventh century, not from him of the Nine Hostages, but from King Niall of the Black
