The subsidiary titles of the Duke of Manchester are: Earl of Manchester (created 1626), Viscount Mandeville (1620) and Baron Montagu of Kimbolton (1620). The dukedom itself is in the Peerage of Great Britain, but all of the subsidiary titles are in the Peerage of England.

His successor, the fourth Earl, who became Duke of Manchester, served as a Privy Counsellor and as a diplomat.
