Despite his youth, John fought in Gascony for Edward III in 1345 and married Lady Elizabeth de Stafford (1342 – 7 August 1375) - widow of Fulk le Strange (Baron Strange) and daughter of Ralph Stafford, 1st Earl of Stafford and Margaret de Audley, a daughter of Hugh de Audley, 1st Earl of Gloucester.
