Origins[edit]
Born before 1389, he was the only surviving son and heir of Sir Thomas Bromflete (died 31 December 1430), who served three times as High Sheriff of Yorkshire, and his wife Margaret St John (died 22 October 1407). She was the only daughter and heiress of Sir Edward St John (died 7 March 1389), of Londesborough, and his wife Anastasia Aton, daughter and co-heiress of Sir Gilbert Aton.[1]
Career[edit]
In 1412 he was appointed to the Royal Household of King Henry IV as an Esquire of the King's Chamber with an income for life of 33 pounds (equivalent to about 28,000 pounds in 2022). When the next King Henry V launched an expedition against France in 1415, he joined as a gentleman leading 12 pikemen and 36 archers under the command of Sir Hartung von Klux. By April 1416 he had married the widow of the first Duke of York, the young king's great-uncle. Knighted before 1419, he served on the king's staff in France until after June 1421. Back in England he participated in local government, sitting on county commissions, and also had a first diplomatic appointment for negotiations with Scotland in 1430.[1]
On the last day of that year his father died and he inherited not only his lands but also his mother's share in the Aton lands, which included those descended from the last Baron Vescy (killed over 100 years earlier at the battle of Bannockburn in 1314). In February 1432 he was one of two ambassadors negotiating with France and in November started a year's term as Sheriff of Yorkshire and Constable of York Castle. When that ended, he volunteered to be one of England's ambassadors to the General Council of the Catholic Church at Basel, now in Switzerland. In 1437 he was again on diplomatic duty in France as a member of the king's Council there, for King Henry VI of England had been crowned as King of France in 1431, and negotiated to end the war. From 1437 he also attended some meetings of the Privy Council of England, but was never sworn as a member.[1]
In 1449 he received a writ to attend the Parliament of England as Baron Vessy, and continued to be summoned until 1467, though in 1456 he obtained permission to be absent unless he wished and in 1462 was excused for life. At a local level he sought to develop his scattered estates, for example in 1458 he obtained permission for a weekly market and two annual trade fairs at Market Weighton and the right to fish freely in parts of the River Humber. During the first phase of the Wars of the Roses, he supported the ruling Lancastrian side and in July 1460 was one of the barons involved in the siege of the Tower of London, but with the victory of King Edward IV he rallied to the Yorkist side. He died on 16 January 1469 and was buried at the church of the Whitefriars in London.[1]
