Duncan
A Scottish surname from a Gaelic personal name meaning “brown-haired warrior” or “dark chief,” originally used as a given name before becoming hereditary.
The #212 most common surname in the United States (2010 Census) — about 1 in every 2,284 Americans shares it.
Etymology
The surname Duncan comes from an old Gaelic personal name, usually explained as Donnchadh. Older references gloss it as “brown head” or “brown-haired,” from Gaelic elements meaning dark or brown plus a personal-name ending. It began as a given name in Scotland and later became a hereditary surname, often used in patronymic forms such as Mac Dhonnchaidh.
History
Duncan is long associated with Scotland and appears early as a personal name before the surname became fixed. It is well known from medieval Scottish history through King Duncan I, whose name helped keep the form familiar across the centuries. In English-speaking countries the surname also generated shortened or altered forms such as Dunkin and Donkin.
