由来と歴史

From the Scottish Gaelic 'Donnchadh', composed of 'donn' (brown, dark; or chieftain) and 'cath' (battle) — meaning 'brown warrior' or 'dark battle'. Donnchadh was a royal Pictish and Scottish name borne by two Kings of Scotland, most famously Duncan I (d. 1040), killed by Macbeth and immortalised in Shakespeare's play. The anglicised form Duncan was adopted as a surname by descendants of those bearing the given name, and the clan Donnachaidh (Robertson) traces its ancestry to a fourteenth-century Donnchadh of Atholl. Duncan is most concentrated in Perthshire, Angus, and the Hebrides.
