Baron Fermoy is a title in thePeerage of Ireland. The title was created byQueen Victoria byletters patent of 10 September 1856 forEdmond Roche.

Previous letters patent had been issued on 14 May 1855 which purported to create this barony for Roche, but these were ruled invalid in 1856. Under theActs of Union 1800, three pre-1801 Irish peerages had to go extinct for each new Irish peerage created. The three extinct peerages cited in 1855 were ViscountsMelbourne andTyrconnel, and theEarl of Mountrath. However, although the earldom went extinct in 1802 with the death of the7th Earl of Mountrath, thesubsidiary title ofBaron Castle Coote passed byspecial remainder and remained extant (until 1827). As a result, theCommittee for Privileges of theHouse of Lords reasoned that while the number of peerages had reduced in 1802, the number of peers had not, thus the 1855 patent was incompatible with the terms of the Act of Union. The 1856 patent substitutedViscount O'Neill for Earl of Mountrath and was accepted.^[1]

The first baron representedCounty Cork and thenMarylebone in the BritishHouse of Commons, taking theChiltern Hundreds the day the spurious 1855 patent was issued. He also served asLord Lieutenant of County Cork. His younger son, the third baron, sat as an Irish nationalistMember of Parliament forKerry East. He was succeeded by his son, the fourth baron, who representedKing's Lynn in parliament as aConservative. The title is currently^[when?] held by his grandson, the sixth Baron Fermoy, who succeeded his father in 1984.^{[citation needed]}

The family seat is Nethercote House, near Nethercote,Warwickshire. The first baron was named after his relativeEdmund Burke.

Diana, Princess of Wales, was a great-great-granddaughter of the 1st Baron Fermoy through her mother,Frances Shand Kydd. Shand Kydd was the younger daughter ofMaurice Roche, 4th Baron Fermoy, a friend ofKing George VI and the elder of the twin sons of the American heiressFrances Ellen Work and her first husband,James Boothby Burke Roche, who, after their divorce, became the 3rd Baron Fermoy. Diana's maternal grandmother,Ruth Roche, Baroness Fermoy, was a confidante and lady-in-waiting toQueen Elizabeth The Queen Mother, and the founder of the annualKing's Lynn Festival (of classical music) inNorfolk, England.
