Gilla na Grakin (Gilla na g-croicean), "the fellow (or youth) of the skins,"—i. e., the serving man of the skins. This word "Gilla" enters into the formation of many Gaelic names, such as Gilchrist, Gilfillin, MacGillacuddy.
Grúagach (pronounced Gróoagach), "the hairy one," from grúag, hair. We are more likely to be justified in finding a solar agent concealed in the person of the laughing Gruagach or the Gruagach of tricks than in many of the sun-myths put forth by some modern writers.

Iron-back-without-action (Ton iaran gan tapuil).

Oisin. In the Gaelic of Ireland this name is accented on the last syllable; in that of Scotland on the first, which gives in English Ossian, the poet made known to the world by Macpherson. The poems of Ossian are of course nothing more nor less than the ballads of Fin MacCumhail and the Fenians of Erin, taken from Ireland to Scotland by the Gael when they settled in the latter country, and modified in some degree by Macpherson. Oisin is pronounced Ushéen in Ireland, u sounded as in but.
Ri Fohín (Ri fo thuinn), "king under the wave."
