Means "black raven" in Irish. In Irish legend this was a board game played by the heroes and gods. It was also the name of a king of Leinster (whom the 'Annals of Ulster' say died in 604); he was a good friend of Mongán of the Dál nAraidi but coveted Mongán's wife, Dubh Lacha. "He tricked Mongán into giving him Dubh Lacha although Mongán, the son of Manannán mac Lir, used his magic powers to get her back. Brandubh treacherously slew the son of the High King Aedh and Aedh made war on him. Brandubh sent a spy to kill Aedh but was later slain by Saran. A Christian embellishment has Brandubh raised from the dead by a miracle."
