of the next year, and only came to a halt with a battle at Salisbury's manor of Stamford Bridge, near York on 31 October 1454. Thomas and John confronted, and decisively beat, Egremont and Richard Percy, whom the Nevilles captured. Marriage John Neville married Isabel Ingoldsthorpe (c.1441 – 20 May 1476), of Burrough Green and Sawston, Cambridgeshire, on 25 April 1457; Archbishop Thomas Bourchier officiated the marriage at Canterbury Cathedral. Isabel was not only the heiress of her father, Sir Edmund Ingoldsthorpe (who had died on 2 September 1456), but also the heiress of her maternal uncle, John Tiptoft and his Earldom of Worcester. It may have been that Earl of Worcester had engineered the match. A letter to John Paston on 1 May 1457 described how "the Erle [of Warwick's] yonger broþere maryed to Ser Edmund Ynglthorp's doughter upon Seynt Markes Day; the Erle of Worcestre broght aboute the maryage." She was a greater heiress than might have been expected for a youngest son like John. John was granted seven southern manors by his father and mother, the Earl and Countess of Salisbury, for his part. John Neville's marriage caused a dispute with Queen Margaret: even though Isabel was over fourteen years old (and therefore of legal age), the Queen claimed that Isabel was still her ward. As a result, Queen Margaret insisted that John pay her a fine for his marriage to Isabel: he was bound to pay her £1,000 in ten instalments. Wars of the Roses The king had become incapacitated in August 1453, which had led to the Duke of York being appointed protector and controlling the government. By Christmas of 1454, however, King Henry had recovered from his illness, which removed the basis for York's authority. Having reconvened the court at Westminster by mid-April 1455, Henry and a select council of nobles decided to hold a great council at Leicester. York and the Nevilles anticipated that Somerset would bring charges against them at this assembly. John Neville included, they gathered an armed retinue and marched to stop the royal party from reaching Leicester, intercepting them at St Albans. Although only a small affray, it resulted in the deaths of some important people; viz. the Duke of Somerset, the Earl of Northumberland, and Lord Clifford. It has been suggested that, whilst Somerset might have been targeted by York, the latter too might have been intentionally slain
