Thank you for this good list.
It should be mentioned in the list that the 17th Duke of Norfolk was originally excepted as Earl Marshal until his death on 24 June 2002. He was succeeded by the 18th Duke of Norfolk who was excepted until being excluded in 2026.
The note "to be created a life peer" should be added for Viscount Colville of Culross, Lord Ravensdale and Lord Hampton.
