Sir Thomas Hungerford of Rowden (died 1469), the eldest son of Robert Hungerford, 3rd Baron Hungerford, lived chiefly at Rowden, near Chippenham, Wiltshire. After giving some support to Edward IV and the Yorkists he joined in Warwick's conspiracy to restore Henry VI in 1469, was attainted, and was executed at Salisbury, Wiltshire. He was buried in the chapel of Farleigh Castle.
Sir Thomas married Anne, daughter of Henry Percy, 2nd Earl of Northumberland, who married two husbands after his death—Sir Lawrence Raynesford and Sir Hugh Vaughan—and, dying on 5 July 1522, was buried in St. Margaret's Church, Westminster.
Sir Thomas left by Anne an only child, Mary, 4th Baroness Hungerford, who became the ward of William, Lord Hastings, and in 1480 married Sir Edward (afterwards Lord) Hastings, her guardian's son. The attainders on her father and grandfather were reversed in her favour in 1485, and her husband was summoned to Parliament as Lord Hungerford. George Hastings, 1st Earl of Huntingdon, was her son.
