The next group is connected with a _Fearchar Abraruadh_ son of _Feradach Finn_, and therefore a brother of Fearchar Fada, but unknown to history, and the only genealogy preserved is that of the _Clan Gillaeoin_ or Macleans. This genealogy is given with so much minuteness up to a certain _Sean Dubhgal Sgoinne_, or Old Dugald of Scone, and the ecclesiastical character of the upper links are so obvious, that it is difficult to avoid regarding it as so far trustworthy. This Dubhgal has a son Raingce; and he has three sons—_Cuduilig_, abbot of Leasamor, that is, lay abbot of the monastery of Lismore in Argyllshire, from whom descended _Gillaeoin_, the eponymus of the clan; _Cuchatha_, from whom sprang the _Clan Chonchatha_, in the district of Lennox, by whom possibly the Colquhouns are meant; and _Cusithe_, from whom came the _Clan Consithe_ of Fife, which has not been identified. According to the usual calculation, old Dugald of Scone must have flourished about 1100, and in a perambulation of the lands of Kyrknesse and Lochow, in the district of Fortrenn, not long after that date, we find the arbiters were Constantine earl of Fife, Magnus Judex or _Mormaer_ in Scotland, Dufgal, son of Mocche, who was aged, just, and venerable (_senex, justus, et venerabilis_), and Meldoinneth son of Machedath, a good and discreet judge (_judex bonus et discretus_).[471] It can hardly be doubted that this Dufgal senex is the _Sean Dubhgal_ of Scone of the pedigree, but in that genealogy he is made the son not of Mocche but of Fearchar Abraruadh, who must be placed four centuries earlier. The next group is brought from _Domnaill Duinn_, son of _Fearadhach Finn_, and consists of the _Clan Labhran_, or Maclarens, and the Clan Aidh. The _Clan Labhran_ are deduced from an abbot of Achtus, by which no doubt Achtow in Balquhidder, where this clan had its seat, is meant, and his pedigree is deduced from Domnall Og, son of Domnall Duinn. According to the usual computation, Domnall Oig must be placed in the ninth century, thus contemporary with Kenneth MacAlpin, while his father is made brother of Fearchar Fada, who died in 697. The same remark applies to the genealogy of the clan Aidh. They cannot be identified with any modern clan, but a Gillamithil, son of Aidh, the eponymus of the clan, falls about the same time with Gillemychel M‘Ath, father of Duncan, who, in 1232, excambs a davach of land in Strathardel, called Petcarene, with the bishop of Moray for the lands of Dolays Michel in Strathspey.[472]
