The title Viscount Newark has been created twice, both times with the subsidiary title of Baron Pierrepont.
The first creation was in 1628 in the Peerage of England for Robert Pierrepont. The first Viscount was created Earl of Kingston-upon-Hull in 1628, and the third Earl was created Duke of Kingston-upon-Hull in 1715 in the Peerage of Great Britain. All the titles became extinct upon the death of the second Duke in 1773.
The second creation was on 23 July 1796 in the Peerage of Great Britain for Charles Pierrepont.[1] The first Viscount was the grandson of The 1st Duke of Kingston-upon-Hull, and was named as the heir of the second Duke in his will. The first Viscount succeeded to the Duke's estates (though not his title) on the death of the Duchess of Kingston in 1788. He was created Earl Manvers in 1806 in the Peerage of the United Kingdom. The titles became extinct upon the death of the sixth Earl in 1955.
