Duncan (given name) Duncan (given name) Duncan is a given name. It is an Anglicised form of the Gaelic "Donnchadh". The final letter "n" in the Anglicised "Duncan" seems to be a result of confusion in the Latin form of the name—"Duncanus"—with the Gaelic word "ceann", meaning "head". One opinion is that the Gaelic "Donnchadh" is composed of the elements "donn", meaning "dark or dark-haired man" or "chieftain"; and "cath", meaning "battle", together meaning "dark-haired or dark warrior". Another opinion is that the Gaelic "Donnchadh" is composed of the elements "donn", meaning "brown"; and "chadh", meaning "chief" or "noble". In royalty: In sports:
