The clans that come first in order in Mr Skene’s classification are those whose progenitor is said by the genealogists to have been the fabulous Irish King Conn “of the hundred battles.” They are mostly all located in the Western Islands and Highlands, and are said by Mr Skene to have been descended from the _Gallgael_, or Gaelic pirates or rovers, who are said to have been so called to distinguish them from the Norwegian and Danish _Fingall_ and _Dugall_, or white and black strangers or rovers. Mr Skene advocates strongly the unmixed Gaelic descent of these clans, as indeed he does of almost all the other clans. He endeavours to maintain that the whole of these western clans are of purely Pictish descent, not being mixed with even that of the Dalriadic Scots. We are inclined, however, to agree with Mr Smibert in thinking that the founders of these clans were to a large extent of Irish extraction, though clearly distinguishable from the primitive or Dalriadic Scots, and that from the time of the Scottish conquest they formed intimate relationships with the Northern Picts. “From whatever race,” to quote the judicious remarks of Mr Gregory, “whether Pictish or Scottish, the inhabitants of the Isles, in the reign of Kenneth MacAlpin, were derived, it is clear that the settlements and wars of the Scandinavians in the Hebrides, from the time of Harald Harfager to that of Olave the Red, a period of upwards of two centuries, must have produced a very considerable change in the population. As in all cases of conquest, this change must have been most perceptible in the higher ranks, owing to the natural tendency of invaders to secure their new possessions, where practicable, by matrimonial alliances with the natives. That in the Hebrides a mixture of the Celtic and Scandinavian blood was thus effected at an early period seems highly probable, and by no means inconsistent with the ultimate prevalence of the Celtic language in the mixed race, as all history sufficiently demonstrates. These remarks regarding the population of the Isles apply equally to that of the adjacent mainland districts, which, being so accessible by numerous arms of the sea, could hardly be expected to preserve the blood of their inhabitants unmixed. The extent to which this mixture was carried is a more difficult question, and one which must be left in a great measure to conjecture; but, on the whole, the Celtic race appears to have predominated. It is of more importance to know which of the Scandinavian tribes it was that infused the greatest portion of northern blood into the population of the Isles. The Irish annalists divide the piratical bands, which, in the ninth and following centuries infested Ireland, into two great tribes, styled by these writers _Fiongall_, or white foreigners, and _Dubhgall_, or black foreigners. These are believed to represent, the former the Norwegians, the latter the Danes; and the distinction in the names
