Knight of the Garter. The Complete Peerage vol.IV,p.206,note c. Second son, Sir William supported the house of York in the Battle of Blore Heath in 1459. In 1461, Edward IV made Sir William Stanley the Chamberlain of Chester and Sheriff of Flintshire. He fought for the Yorkists at Hexham in 1466 and was given the Lordship and Castle of Skipton in Yorkshire which he subsequently exchanged for Chirk. He obtained additional land following the battle of Towton. After the battle of Tewkesbury in 1471 he took the news to Queen Margaret of her son's death and then took her to Coventry.
Edward IV's successor, Richard III, courted Sir William's support by various grants of manors and by appointing him Chief Justice for North Wales and Chief Commissioner for Shropshire. Sir William was suspicious of Richard because of the disappearance of the two princes and changed his allegiance to Henry Tudor. At the Battle of Bosworth Field, Stanley rescued Henry at a critical moment in the battle, struck down the King and is said to have found his crown in a thorn bush. He handed the crown to his elder brother Thomas who put it on the head of Henry Tudor. Henry VII appointed Sir William Stanley the Lord Chamberlain and Knight of the Garter and granted him additional lands that made him the richest commoner in England. Sir William's wealth and power inevitably attracted enemies and he was disappointed that his services had not led to a peerage. In 1489 he became Constable of Caernarvon and Beaumaris, and in 1490 Henry VII gave him the Lordships of Bromfield, Chirk and the castles of Dinas Bran, Holt and Chirk in confirmation of earlier grants of the latter two by Richard III.
Sir William as Lord Chancellor was arbitrator in the dispute between Sir John Stanley of Elford and his half-brother Sir Humphrey, mentioned above. He then bought the manors of Aldford and Nether Alderley in Cheshire from Sir John. Sir William was arrested and imprisoned in the Tower of London in 1494, on suspicion of being involved in the rebellion of Perkin Warbeck, who claimed to be the younger of the "princes in the tower" and therefore heir to Edward IV. At that time it was not known that the sons of Edward IV had both been murdered. Although Sir William had helped put Henry VII on the throne he was known to have been a strong supporter of Edward IV. He was quoted as saying that if Perkin Warbeck was the son of Edward IV he would not fight against him. This, and his unwillingness to confirm or deny his guilt, was sufficient to see him executed at the Tower on 16 Feb 1495.57964
