However, they had no children and Winchilsea was succeeded by his uncle, the 5th Earl. He had earlier represented Hythe in Parliament. He was childless and was succeeded by his half-brother, the 6th Earl. He never married and on his death in 1729 the Barony of FitzHerbert of Eastwell became extinct. He was succeeded in the remaining titles by his second cousin the 2nd Earl of Nottingham, who became the seventh Earl of Winchilsea as well (see below for earlier history of this branch of the family). He was a noted statesman and served as First Lord of the Admiralty, Secretary of State for the Southern Department, Secretary of State for the Northern Department and as Lord President of the Council. On his death the titles passed to his eldest son, the 8th Earl of Winchilsea. He was also a politician and held office as First Lord of the Admiralty and as Lord President of the Council.
