Since the 5th Duke of Beaufort had purchased the Usk estate in 1771, he and the Morgan family of Tredegar possessed about equal estates in the county (said to be worth about £12,000 p.a. in 1795).
The Tredegar interest was represented by John Morgan; on his death in 1792 by his nephew-in-law Robert Salusbury; and from 1796 by his nephew and heir Charles Morgan, who held the seat until 1831. While John Morgan had resented the growing influence of the Duke of Beaufort and gone into opposition when Beaufort was awarded the lieutenancy of Brecon in addition to that of Monmouth in 1787, his nephew collaborated with Beaufort to preserve the peace, which entailed supporting Beaufort in the boroughs seat and, in turn, receiving Beaufort’s support in Breconshire.
