Renaud de Courtenay
Renaud de Courtenay, anglicised to Reginald I de Courtenay, of Sutton, Berkshire, was a French nobleman of the House of Courtenay who took up residence in England and founded the English Courtenay family, who became Earls of Devon in 1335. The title is still held today, by his direct male descendant.
He was the son of Miles (Milo) de Courtenay, Seigneur (lord of the manor) of Courtenay, in the Kingdom of France, today in the Loiret department in north-central France, by his wife Ermengard de Nevers.
He succeeded his father as Seigneur of Courtenay. He fought in the Second Crusade, with King Louis VII of France. He quarrelled with King Louis VII, who seized Renaud's French possessions and gave them along with Renaud's daughter Elizabeth to his youngest brother, Pierre (Peter) of France, who thenceforth became known as Peter I of Courtenay (died 1183)). He became Lord of the Manor of Sutton in 1161.
