Gaelic Dughall, Middle Gaelic. Dowgall, Dubgaill (gen., 1467 MS.). The Old Irish form of the name is Dubgall, "black stranger,' a 'Dane.' With 'Mac' we have Macdoual and Macdougal, which see. Dufgal occurs on a runic stone in the Isle of Man as Tufcal, and in the form Duggall it is found in Norse Konunga Sogur (p. 332). Dufgal filius Mocche, 'senex, justus, et venerabilis,' appears in a complaint by the monks of St. Serf's Island in Loch Leven c. 1128 (RPSA., p. 117). Reeves (Culdees, p. 130) says this Dufgal "resembles the old Dubhgall of Scone who is mentioned in the Irish tract on the men of Alba preserved in the Book of Ballymote and in MacFirbis genealogical MS. Old Dubhgall was father of Raingce whose son Aiscdhe was a progenitor of Clann Considhe in Bib" (Fife). But he occurs too high in the pedigree to admit of his being contemporary with King David, 1124—53. In the Gaelic genealogical MS. of 1467 'Ruingr me Sean Dubgall' is given as one of the ancestors of the Macleans. Duuegall, brother of Maldouen son of Alwin, earl of Levenax, witnessed the earl's gift of the church of Kamsi (Campsie) to S. Kentigern c. 1208—14, and as Duuegallus he appears c. 1208—33 (REG., p. 80, 93). Dugal, canon of Dunblane, was afterwards bishop (Inchaffray, p. 260), and Dugall, thane of Molen, 1261, was one of the inquisition on the king's garden at Elgin and the lands belonging to it (APS., I, p. 101 red). Patrick Dougale was burgess of Ayr, 1415 (Ayr, p. 11), and Edward Dougall was witness in Perth c. 1552 (Rollok, 114). Fraser (Wardlow, p. 81) spells the name Duellus, and Doul or Dowill appears for Dougal, 1511, in a bond of man-rent (SCM., IV, p. 195). The devocalization of -ll final suggested to non-Gaelic ears that a d or t followed, hence the spelling Dugald, and in caricature Tugalt. Dowgal 1527.

(Celtic) Black or Dark Stranger [Gaelic and Irish Dubhghall—dubh, black, dark + the aspirated form of gall, a stranger]

(Generally Mac-Dougall). Gael, dhu, black, and gall, a stranger-an expression used by the Celtic inhabitants of Scotland to denote a Lowlander, or any one not of their own race. It is still in use as a baptismal name.

(Gaelic and Celtic.) The black stranger, from Dhu, black, and gall, a stranger, a term used by the Celts to denote a Lowlander, a foreigner, not one of them. The Danes, Swedes, and Norwegians were called by the Irish Fionne Gael, or fair—haired, and the Germans "Dubh Gail,"or the black strangers.
