In page Gower Peninsula:

"

Following the Norman invasion of Wales the commote of Gŵyr passed into the hands of English-speaking barons, and its southern part soon became Anglicised.[citation needed] In 1203 King John (1199–1216) granted the Lordship of Gower to William III de Braose (died 1211) for the service of one knight's fee.[1] It remained with the Braose family until the death of William de Braose, 2nd Baron Braose in 1326, when it passed from the family to the husband of one of his two daughters and co-heiresses, Aline and Joan.[citation needed] In 1215 a local lord, Rhys Gryg of Deheubarth, claimed control of the peninsula, but in 1220 he ceded control to the Anglo-Norman lords, perhaps on the orders of his overlord, Llywelyn ap Iorwerth.[citation needed]
