The next group consists of the supposed descendants of Colla Uais, son of Eochaidh Doimlein, king of Ireland, and comprised the clans descended from Somerled, the petty king of the great district of Argyll in the reign of Malcolm the Fourth. These genealogies, as far back as their great ancestor Somerled, are undoubtedly authentic. His father _Gillabride_, and his grandfather _Gillaadomnan_, both purely Gaelic forms, rest on the authority of the Irish Annals, and _Imergi_, the grandfather of the latter, is probably the Jehmarc, who appears as a Celtic petty king in the year 1031. Beyond this we have no fixed date, but between him and Colla Uais, whose death is placed at 323, we have only seven names given for a period of 700 years, or one hundred years to a generation, which is impossible, and betrays the artificial character of this part of the pedigree. The third group consists of clans supposed to be descended from the Hy Neill or race of _Neill naoi giallach_, king of Ireland, which brings us nearer historical times. They consist of the Lamonds, the Clan Lachlan, the MacEwens of Otter, and a Clan _Somairle_ which has not been identified. These clans are all taken back to a certain Aoda Alain, termed _Buirche_, son of Anrotan, son of _Aodha Atlamuin_, ancestors of the O’Neills. From Aoda’s son Gillacrist the Clan Lachlan came, and from another son Duinsleibe the Lamonds, MacEwens, and Clan Somairle. The genealogy of the Lamonds is authentic as far back as Fearchar, the son of Duinsleibe, but Ferchar’s son and grandson are mentioned in a charter in 1246,[470] while the death of Aodha Alain is recorded in 1047, and thus only three generations are placed in two centuries. This derivation too involves the difficulty of supposing that Cowall was peopled from Ireland in the eleventh century, a colony of which there is not a trace in history; but as these clans are locally grouped together we may accept the genealogies as indicating that they had a common origin. The fourth group consists of the old earls of Lennox and Mar, said to be descended from _Maine Leamna_ and _Cairbre Cruithneach_, sons of Corc, son of Lughaigh, king of Munster; but the artificial character of this descent is here very apparent, for Ailin, the first earl of Lennox, who lived in the beginning of the thirteenth century, is made the great-grandson of _Maine Leamna_, whose father was a contemporary of Saint Patrick in the fifth century.
