Meaning and Etymology
The surname Byrne is an anglicized form of the Gaelic patronymic Ó Broin, meaning “descendant of Bran”. The personal name Bran is derived from the Irish word bran, meaning “raven” (FamilySearch). In some cases the spelling may also derive from Ó Birn, “descendant of Biorn”, the Irish form of the Old Norse personal name Bjǫrn (FamilySearch). Additionally, the spelling Byrne can arise independently as an English variant of the surnames Berne or Burn, which are locational or topographic in origin (FamilySearch).
Multiple Origins
Thus the surname Byrne has at least two documented linguistic origins: (1) Irish patronymic Ó Broin (descendant of Bran, “raven”) and (2) English variant of Berne or Burn.
