eponymous ancestors of the various Uí Néill dynasties: Eógan of the Cenél nEógain and Conall Gulban of the Cenél Conaill, making up the northern Uí Néill; Fiachu of the Cenél Fiachach dynasty, Lóegaire (the king who Saint Patrick is said to have converted) of the Cenél Lóegaire, Maine of the Uí Maine, Eógan of the Cenél nEógain, Conall Cremthainne of the Clann Cholmáin and the Síl nÁedo Sláine, and Coirpre of the Cenél Coirpri, making up the southern Uí Néill. The O'Higgins family claims descent from the Southern branch of Uí Néill. Famous descendants include Niall's great-great-grandson Saint Columba, Saint Máel Ruba, the Kings of Ailech, the Kings of Tir Eogain, and the Kings of Tír Conaill. The Scottish Clan Ewen of Otter, Gilchrist; Clan Lamont; the MacSorleys of Monydrain, (of Clan MacDonald of Dunnyveg a branch of Clan Donald); Clan Maclachlan; Clan MacNeil, and the MacSweens all claim a descent from an Irish prince of the O'Neill dynasty, Ánrothán Ua Néill/Anrothan O'Neill, son of Áed, son of Flaithbertach Ua Néill, King of Ailech and Cenél nEógain, who left Ireland for Kintyre in the 11th century and died 1036. As next-generation sequencing has become available, various chief lines have been tested. Although these studies are not coordinated with each other and are ongoing, it is already apparent that not all of these lineages are related to each other within Niall's timeframe. For instance, the chiefs of Clan Donald are now known to belong to a branch of Haplogroup R1a, which split from Niall's hypothetical lineage over 20,000 years ago. Y Chromosome Analysis Following a 2006 hypothesis by Moore et al. suggesting that his Y chromosomal signature had been discovered, popular science journalists and genetic testing companies began promoting the theory that millions alive today have an unbroken descent from Niall. Geneticists at Trinity College Dublin found that 21 percent of men from north-western Ireland, 8 percent from all of Ireland, a substantial percentage of men from western and central Scotland, and about 2 percent of men from New York bore the same Y-chromosome haplotype. The geneticists estimated that about 2–3 million men bear this haplotype. Moore et al. concluded that these men descend from "a single early-medieval progenitor" and implied this was associated with Niall's dynasty. While Moore et al. did not specifically state that Niall was the progenitor of M222, journalists quickly jumped to that conclusion. According to the
