Douglas surname meaning

Douglas is chiefly a Scottish habitational surname from places called Douglas. The name is traditionally analyzed from Gaelic Dubhghlas, often glossed as “dark stream” or “dark water,” and several Scottish localities preserve the name. Douglass, Duglas, Duglasse, and Dubhghlas show historical and language forms. A place surname can arise independently when people move from different places with the same name, so not every Douglas line belongs to the famous Douglas family or one ancestral valley. Place is the high-confidence catalog type. The landscape gloss explains the place name, while genealogy is needed to identify a particular Douglas origin.
