At the death of Charles Dormer, 2nd earl of Carnarvon, the earldom was extinguished for lack of direct male heirs but the barony of Dormer descended to the nearest male descendant of his grandfather, Robert Dormer†, 1st Baron Dormer. The new Baron Dormer did not inherit the principal family seat at Wing Park; this had passed (in marriage) to Philip Stanhope, later 3rd earl of Chesterfield.
As a Catholic, Dormer was unable to take his seat in the House and his circumscribed political activity was limited to the brief period of religious toleration during the reign of James II; in 1688 he was named as an alderman for Warwick in a charter that was never issued.
