Clan McCorquodale Badge
The surname McCorquodale is an Anglicization of the Gaelic MacThorcadail (or MacCorcadail), meaning "son of Torcadal". The Gaelic personal name Torcadal is of Norse origin and means "Thor's kettle". In 1881, the surname was most frequent in lands which constitute the current Paisley postcode area. This, more or less, corresponds with the Clan McCorquodale's traditional lands in Argyll.
The founder of the clan, according to legend, was a Thorkil (Torcadal) who was a member of the Scots army under Kenneth MacAlpin. The legendary story states that Alpin, father of Kenneth MacAlpin, was killed in battle, and his head was carried off by enemy Picts. Alpin's head was then displayed in the Pictish town of Camelon. The story goes on to state that the claimed ancestor of the McCorquodales, Thorkil, recovered Alpin's head. For this deed, Thorkil was said to have been rewarded with lands on Loch Awe side. Be that as it may, the earliest record of the clan occurs in the 15th century.
Eilean-a-Bharain ("the baron's island") on Loch Tromlee. The ruinous castle upon the island was once the seat of the chiefs of Clan McCorquodale.
