Legendary Celt Branwen
Branwen is the daughter of LLyr and Penarddun, siter of Brand and Manawydan, and half-sister of Nisien and Efnisien. Martholwch of Ireland sued for her hand in marriage to create an alliance between Ireland and Wales. Mathjolwchj returned to Ireland with Branwen, shere, within a year she bore him a son, Gwern. But due to an insult caused by Efnisien, the troublemaking half brother of Branwen, Matholwch grew cold to her and she became almost a slave. Matholwch also prevented any tale of her predicament to reach Wales and her family. So Branwen trained a starling to speak and sent it to Wales, where it told Bran of her plight. Bran set out with his navey to rescue her. Matholwch made peace and promised to abdicate his throne to Gwern but Efnisian slew the child. A great battle began and resulted in nearly the complete destruction of both sides. Realizing that the two kingdoms had been desgtroyued on her account, Branwen sailed to Aber Alaw and died of grief.
