Thomas took part in several of the military campaigns of Edward III. He married, sometime before 10 June 1350, Maud de Ufford, daughter and heir of Sir Ralph de Ufford and Maud of Lancaster, the daughter of Henry of Lancaster, grandson of King Henry III.[1] After Thomas's death, his widow was indicted for involvement in a plot against King Henry IV, but was later pardoned.[2] When Thomas died in 1371, he was succeeded by his only son, Robert de Vere, 9th Earl of Oxford.
