Galbraith

The surname Galbraith is derived from the Gaelic elements gall, meaning "stranger", and Breathnach, meaning "Briton".[1] As such, the surname can be taken to mean "British foreigner",[2] "British Scandinavian",[3] "foreign Briton",[4] or "stranger-Briton".[5] The surname Galbraith can be rendered in Scottish Gaelic as Mac a' Bhreatannaich.[6]

The surname is borne by members of Clan Galbraith.[7] The clan is known in Gaelic as Clann a' Bhreatannaich.[4] The earliest recorded chief of this family may be "Gillcrist Bretnach", a man attested in 1193.[8] This man's name could indicate that he was either of Welsh[9] or North British ancestry.[10]
