The House of Percy (old french Perci) were the most powerful noble family in Northern England for much of the Middle Ages, having gained the title Baron Percy already in 1066. The name derives from the village of Percy-en-Auge in Normandy, the initial home of the family prior to the Norman Conquest. Members have held the titles of Earl of Northumberland or Duke of Northumberland to this day. In common with their rivals, the House of Neville, the Percy surname was adopted through marriage to an heiress. Whilst their Neville inlaws and rivals were originally from the Scottish House of Dunkeld, the Percys were descended from Joscelin of Louvain, son of Godfrey I, Count of Leuven and Agnes Percy, daughter of William de Percy and Adelaide de Clare.
