The accompanying text in 'The Clans of the Scottish Highlands' by James Logan begins as follows: "CLANN NAN GUINNAICH, OR GUNNS The Gunns were in the north the counterpart of the MacGregors in the south. Although not numerous, they were most martial and resolute, and the appellation by which they were distinguished is very indicative of their general character. Guinneach signifies sharp, keen, fierce, and was doubtless imposed as descriptive of their known or imputed dispositions. The genealogical derivation of the clan is from Guinn, the second son of Olaus or Ollav the Black, King of Man and the Isles, who died in the year 1237."
