Note 91 — THE BOOK OF THE DEAN OF LISMORE.

A valley in the eastern part of Perthshire, where the grave of Diarmad is pointed out to this day. M’Rorie appears to have been an inhabitant of the neighbourhood, for he speaks of Glenshee as being close beside him. The name of Glenshee is derived from the word “Gleann,” a valley, and “sìth,” a hill of a peculiar form. This word is found in the names of several Scottish hills, as “Sìth challain,” Schihallion; “Beinn shìth,” Ben Hi; “An t-Sìth mhòr,” the great pointed hill. “Sìthan,” a hillock. The word has been often mistaken for “Sìth,” peace, whence the name “Sitheach, sithichean,” a fairy, fairies, has been absurdly rendered the peace folk, instead of the folk of the hills, referring to their reputed residence in earthen mounds.
