Lir, Llyr Half-Speech
A King of Britain, the father of Bendigeid Vran, Branwen and Manawyddan. In origin he was the Welsh sea deity.
He is listed in two paternal pedigrees found in Bonedd yr arwr as the direct descendant of Arthur, though the genealogies themselves differ quite markedly. However, when studied more closely, it becomes obvious that the pedigree that appears first in the work has skipped three generations.
Another interesting paternal pedigree for Arthur, which names his descent as direct from Llyr, is to be found in the Mostyn MS 117. When the three lines of descent are compared, it is not hard to see that all three are obviously based on the same source material.
Note
The Welsh word llyr means ‘sea.’
