=== Life Sketch ===
About 1033, Anrothan O'Neill, resigned as King of Aileach in favor of his brother Domhnall and moved to Kintyre where he married a princess of a local king; she brought as a dowry the lands of Cowal which is the peninsula lying between Loch Fyne, the Firth of Clyde and Loch Long, and also the lands of Knapdale which lies on the western side of Loch Fyne. From old Gaelic manuscripts, the family Maclachlan of Maclachlan can claim descent from Anrothan and the Kings of Aileach and High Kings of Ireland.
Child of Anraddan/Anrothan and Scottish Heiress is:
. Aed Alainn an buirrche.
The Ui Neill were the great royal tribal dynasty of the North Gaels. Having separated from the royal kinsmen, the Connachta, shortly after the career of their illustrious fifth century ancestor Niall of the Nine Hostages, theyset out from a base in Sligo and soon (by the beginning of the 6th century) monopolised the Sacral High-Kingship of Tara, which for hundreds of years they alternated between their own 2 illustrious branches, the Northern Ui Neill and the Southern Ui Neill.
The Cineal Eoghan (a clan of the Northern Ui Neill) were the Royal Clan of the North Gaels, associated withthe High-Kingship of Tara. Their original patrimony included the modern baronies of Raphoe and Irishowen in Donegal, but from their centre at the great fort of Ailech in Irishowen, they soon spread through Derry and much Tyrone as well. (Tyrone, Gaelic "Tir Eoghain", the land of Eoghain, is named for them.) The great O'Neills themselves descend from Niall Glundubh, High-King of Ireland, who fell fighting against the Vikings near Dublin in 919. His grandson, Domhnall was the first to bear the dynastic name of O'Neill. The were the chief family of the Cineal Eoghain.
The MacLachlan, Lamonts, and MacSweens descend from Niall Glundubh, High-King of Ireland (thus descend from Aed Finlaith, King of Ireland and Kenneth mac Alpin, King of Scots, through his daughter, MaelMuire). The MacSweens descend from Suibhne, son of Dunsleve O'Neill, Lord of Knapdale. They descend from Anrothan O'Neill, the Ulster prince who in the first half of the eleventh century married the joint heiress of the Cineal Comhgall (after whom Cowall is named) and their collateral kinsmen the Cineal nGabran of Knapdale. His 2 grandsons, Donnshleibhe (Dunsleve) and Domhnall (Donald) O'Neill are the ancestors of the branches of the clan. From Dunsleve, lord of Knapdale, are descended the MacLachlans, Lamonts, MacSorleys, MacSweeneys, MacQueens or MacSweens and the MacEwens.
