Prince Gwalchafed of Gododdin
(Born c.AD 500)
(Welsh: Gwalchafed; Latin: Walgabetius; English: Gareth)

According to Welsh folklore, Gwalchafed, meaning Falcon of Summer, was the son of Gwyar (alias King Letan of Gododdin) and younger brother of the celebrated warrior, Gawain alias Gwalchmai, with whom he is said to have served at the court of their maternal uncle, the High-King Arthur. Some historians think him to be the original Sir Galahad. However, a precursor of one of Gawain's brothers named in later literary sources -  Agravaine, Gaheris and Gareth - would seem more likely. There is no need to choose between the last two whose names are so similar to Gwalchafed however. They appear to originally have been the same person.
