Seoirse Brún (George Browne), was an Irish scribe, fl. 1876. Brún, a native of Creggduff, Annaghdown, County Galway, is known only from a manuscript called RBÉ F006. It contains the following note:
George Browne Cregg Duff This Book/Belongs to him For Certain No Other Person/in This Locality can claim on This/Book but him Alone When he is Dead/and his bones are rotten This Little Book/Will tell his Name when he is quite/Forgotten Given under My ha[n]d this 18th Day of Oct 1876 - George Browne/Cregg Duff Annadown/County of Galway Ireland, The European Iliad.
The Annaghdown-Headford has Irish speakers as of 2009. He may have been descended from one of The Tribes of Galway, the family Browne.
