Gwyn Gohoyw ap Gloyw Gwallt Lydan

Gwyn Gohoyw appears, in the Welsh genealogies, to be a real human. He is one of the crossover figures with Welsh mythology, as he is mentioned in the Mabinogion as the father of the wife of Pyderi. Her profile can be found here: Cigfa verch Gwyn Gohoyw, {Fictitious, Mabinogion}
