Blackbourne

Blackbourne is a variant of the surname Blackburn, which itself is a locational surname deriving from the city of Blackburn in Lancashire, England. The name originates from Old English blæc (meaning "black") and burna (meaning "stream"), thus "black stream."

The variant Blackbourne likely arose from dialectal or orthographic variation, as "bourne" is an older spelling of "burn" (stream). The name may sometimes also be a topographic surname for someone living near a dark stream, though the locational origin is primary.
