Aymer de Valence (c. 1265–1324)

English politician. He was appointed guardian of Scotland 1305 by Edward I; he defeated the Scots that year at Methven, but was defeated by Robert Bruce (see Robert I) at Loudon Hill in 1307. In 1314 he was made lieutenant of Scotland, and fought at the Battle of Bannockburn.

He was a nephew of Bishop Aymer de Valence, and inherited the title of Earl of Pembroke 1296. He joined the Lancastrian party, and was a fierce opponent of Piers Gaveston, a favourite of Edward II, whom he captured in 1312; but was later reconciled to the king.

Aymer de Valence (died 1260)

French cleric. He was a half-brother of the English king Henry III, who obtained for him the position of bishop of Winchester. He repudiated the barons' constitution at the Parliament of Oxford in 1258, and was forced to leave the country.

He was the son of Isabella, widow of King John, and her second husband, Hugh, Count of La Marche.
