Bendigeid Vran
Bendigeidfran, Brān the Blessed
The giant son of Llyr and Penardun and brother Branwen and Manawydan Fab Llyr. Some sources, however, make Bendigeid Vran and Branwen the children of Llyr by Iweriadd, while Manawydan fab Llyr was the son of Llyr by Penardun.
He is more commonly referred to as Brān the Blessed, and his story is told in the Mabinogion.
