  [S6040] FindAGrave Old World, Henry de Percy III 1298–1352. Sir Henry de Percy III - 9th Baron Percy and 2nd Baron Percy of Alnwick. Oldest of two sons of Henry de Percy, 1st Baron Percy of Alnwick, and Eleanor Fitz Alan, daughter of Richard Fitz Alan, 8th Earl of Arundel. Percy's father died in 1314 when Percy was only sixteen, and John de Felton was selected as regent for the Barony. During his reign, King Edward II of England gave Henry lands previously belonging to Patrick IV, Earl of March, in Northumberland, made Henry governor of Pickering Castle and of the town and castle of Scarborough. Henry was later knighted at York. Henry joined in the removal of the Despensers, the family that influenced Edward against his son, Edward III. Percy, along with Sir William la Zouche, helped bring about the Treaty of Edinburgh–Northampton, signed by Robert the Bruce in 1328, ending the war ongoing since 1296. The treaty, which recognized Scotland as an independent country run by Bruce, lasted only five years. Edward III would end the treaty and plunge the two countries back into war. Edward III appointed Percy to his council in 1327, and given the manor and castle of Skipton, as well as the castle and barony of Warkworth in 1328. In 1329, Percy established a chantry to assure safe passage to heaven and to celebrate his divine soul. When the Scottish wars resumed, Percy was at the on Battle of Halidon Hill at Berwick, July 19, 1333, where the Scots took a heavy toll, and Percy was appointed constable of Berwick. Percy also commanded the right wing of the English forces at the Battle of Neville's Cross, October 17, 1346, where the Scotland's King David II was captured. Percy married Idoine de Clifford, daughter of Robert de Clifford, 1st Lord Clifford and Maud de Clare, in 1314 in Yorkshire, England. https://www.findagrave.com/memorial/69559740/henry_de_percy
