What Brittonic dialect was spoken in the kingdom who had the father of Owain mab Urien as king?
Rheged Rheged (] ) was one of the kingdoms of the "Hen Ogledd" ("Old North"), the Brittonic-speaking region of what is now Northern England and southern Scotland, during the post-Roman era and Early Middle Ages. It is recorded in several poetic and bardic sources, although its borders are not described in any of them. Some modern scholars have suggested that it included what is now Cumbria in North West England and possibly extended into Lancashire and Scotland. In some sources, Rheged is intimately associated with the king Urien Rheged and his family. Its inhabitants spoke Cumbric, a Brittonic dialect closely related to Old Welsh.
Aber Alaw Aber Alaw (Welsh: "Mouth of the Alaw" ) is at the mouth of the Afon Alaw on Anglesey, in North Wales. According to the "Mabinogion", it is here that Queen Branwen died of grief after escaping the destruction of Ireland. She and the seven survivors of Prydein (Britain) landed at Talebolyon, and upon seeing the coasts of both Ireland and Prydein, she died of a broken heart, blaming herself for the havoc.
