Percy family


The Percy family is an old English noble family. They were among the oldest and most powerful noble families in Northern England for much of the Middle Ages. The noble family is known for its long rivalry with the House of Neville, another family powerful in northern England during the 15th century. The feud between the two families, known as the Percy-Neville feud led to the Wars of the Roses, at the time known as the Civil Wars, in England.
The House of Percy descends from William de Percy, a Norman who crossed to England after William the Conqueror in early December 1067. William de Percy was created as the 1st feudal baron of Topcliffe in Yorkshire. He was rebuilding York Castle in 1070.
The Percy surname derives from the manor of Percy-en-Auge in Normandy, the home of the Percy family at the time of the Norman Conquest. Family members have held the titles of Earl of Northumberland or Duke of Northumberland to this day, in addition to Baron Percy and others.
The Percy surname twice died out in the male line only to be re-adopted later by the husband or son of a Percy heiress. In the 12th century, the original Percy line was represented by Agnes de Percy, whose son by her husband Joscelin of Louvain adopted the surname. Again in the 18th century, the heiress Elizabeth Seymour married 1st Duke of Northumberland|Sir Hugh Smithson], who adopted the surname Percy and was created Duke of Northumberland.
