Thomas Belasyse, 1st Earl Fauconberg PC was an English peer. He supported the Parliamentary cause in the English Civil War, becoming close to Oliver Cromwell and marrying Cromwell's third daughter, Mary. After the Restoration of the monarchy he became a member of the Privy Council to Charles II and was elevated to an earldom by William III.

John Belasyse, 1st Baron Belasyse was an English nobleman, Royalist officer and Member of Parliament, notable for his role during and after the Civil War. He suffered a long spell of imprisonment during the Popish Plot, although he was never brought to trial. From 1671 until his death he lived in Whitton, near Twickenham in Middlesex. Samuel Pepys was impressed by his collection of paintings, which has long since disappeared.
