The title became extinct on the death of Richard Fiennes 6th Viscount on 29 July 1781.
Under James I of England, William Fiennes, the eighth Baron Saye and Sele, was created Viscount Saye and Sele in the Peerage of England, in 1624.
It was later revived and is currently held by the Twisleton-Wykeham-Fiennes family, descendants of Cecil Fiennes, granddaughter of the second Viscount.
The family of the first Viscount includes: The three eldest sons of the first Viscount served as Members of Parliament, James representing Banbury and then Oxfordshire, Nathaniel for Banbury and John for Morpeth.
The first Viscount's family including sons-in-law took the side of the Parliamentarians in the English Civil War, but the Viscount argued against the execution of the king and this helped his position when the monarchy was restored in 1660.
