[4] Some writers would identify Turgeis with Thorgils, son of Harold Fairhair, who with his brother Frothi went on a viking expedition to Ireland. They captured Dublin, and Thorgils reigned there for a long time as king. In the end, however, he was betrayed by the Irish and was killed. (Heimskringla: Haralds saga hins hárfagra, ch. 35.)
This account of Thorgils certainly bears a resemblance to that of Turgeis contained in the Irish chronicles and Giraldus Cambrensis (cf. Todd: Introduction to War of the Gaedhil with the Gaill, I., ii.), but it is of course incorrect to say that Turgeis was a son of Harold Fairhair.

[8] The Irish chroniclers use a variety of names for the Scandinavians: Dibearccai (outlaws), Gaill (foreigners), Gennti (Gentiles), and Pagánaigh (Pagans). They also distinguish between Danes and Norsemen. The Danes were known as Danair, Danmarcaigh, Dubh Gennti (Black Gentiles), and Dubh-Gaill. The word Dubh-Gaill (Black Foreigners) still survives in the personal names Doyle and MacDowell and in the place-name Baldoyle. The Norsemen were called Finn-Gaill (Fair Foreigners), Finn-Genti, Nortmannai (Lat. Northmanni) and Lochlannaigh (i.e., men of Lochlann or Norway).
