William de Percy
William de Percy, surnamed Gernon or Algernon, took to wife Emma de Port, by whom he had issue three sons: Allen, Walter, and William. He went a journey to Jerusalem, and departed this life at Mountjoy, in the Holy Land. His body was brought home and buried in the Chapter-house at Whitby. His descendants are the Duke of Northumberland, Lord Beverly, and the collateral branches of the name of Percy.
In 1096 CE he joined Robert Curthose, Duke of Normandy, on the first Crusade. He died at Mont-joy, so called by the Christian Pilgrims, because from there they first saw the Holy city.
