The Scottish kingdom of Dalriada was at this time confined within very narrow limits, and could hardly claim a higher position than that of a _Mortuath_, as we find that it consisted of three tribes, termed, in the tract ‘Of the History of the Men of Alban,’ the three powerfuls in Dalriada. These were the _Cinel Gabran_, the _Cinel Angus_, and the _Cinel Loarn_, who traced their descent from the three sons of Eochaidh—Fergus, Angus, and Loarn—who led the colony from Irish Dalriada. We obtain from this tract some valuable information as to the constitution of these tribes. The _Cinel Gabran_ occupied Kintyre in its old extent, including Knapdale, the district of Cowall, and the islands, that is, of Arran and Bute, and consisted of five hundred and sixty houses. The _Cinel Angusa_ possessed Isla and Jura, and consisted of four hundred and thirty houses. The _Cinel Loarn_ possessed the extensive district of Lorn, extending from Lochleven to the Point of Ashnish, and part of the opposite coast of Morvern, and consisted of four hundred and twenty houses. The districts thus occupied by these tribes surrounded an inner region, extending from the range of mountains called Drumalban to the arms of the sea termed Lochs Craignish and Crinan, consisting of the two districts of Lochaw and Ardskeodnish. This inner region seems to have been left to the older inhabitants of the country, and to have borne the name of _Airgialla_, possibly for the same reason that that name was applied to the extensive region in the heart of Ulster, wrested by the Scots under the three Collas from the Irish Picts.[248] The houses of which these three tribes consisted seemed to have formed groups of twenty houses each, as we are told that their sea muster assigned twice seven benches or seats for rowers to each twenty houses, but the armed muster for the _Sluaged_ or hosting was, for the _Cinel Gabran_ three hundred men, for the _Cinel Angusa_ five hundred men, and for the _Cinel Loarn_ seven hundred men, but one hundred of these were furnished by the people of _Airgialla_.[249] [Sidenote: The tribe in Galloway.]
