psychiatric issues; the 6th Duke lived from 1907 until his death in February 1922 in a house in the grounds of Craig House Psychiatric Hospital in Edinburgh. Lord Edward's other older brother was Major Lord Desmond FitzGerald (1888-1916), an officer in the Irish Guards who was accidentally killed during a grenade demonstration at Calais during the First World War. So, Lord Edward inherited the dukedom and what remained of the Carton Estate in February 1922, thus becoming the 7th Duke. In this way, much of the Carton Estate was lost to the FitzGerald dynasty. Carton House and what remained of the Carton Estate was finally sold by the 7th Duke of Leinster and his son, the then Marquess of Kildare (1914-2004), in the late 1940s. It is alleged that, in 1923, a local unit of the IRA went to Carton with the intention of burning it down. However, they were stopped when a member of the FitzGerald family brought a large painting of Lord Edward FitzGerald to the door and pointed out that they would be burning the house of a revered Irish patriot. During the Second World War, Carton House was occupied by the Irish Army who used the building as the headquarters of the 2nd Infantry Division. In 1949 the house was purchased by the 2nd Baron Brocket (1904–1967), a multi-millionaire Tory peer and businessman and a member, by descent, of the ancient Ulster family of Ó Catháin (O'Cahan or O'Kane), whose principal residence was Brocket Hall in Hertfordshire, England. Lord Brocket bequeathed Carton to his younger son, The Hon. David Nall-Cain who, having moved to the Isle of Man, sold the house in 1977 to the Mallaghan family. In 2017 the Mallaghan family sold Carton House to John Mullen for €57 Million. Government decision not to buy the estate From 1977 to 2017, Carton House and Demesne was the property of the Mallaghan family, and in the 1980s and 1990s, the Irish Government came under public and political pressure to buy the house and its grounds but decided not to do so. House as film set The house was used as a film location by many film-makers and broadcasters. Two of the films made there were Stanley Kubrick's Barry Lyndon in 1975 and The Big Red One in 1980. They starred Ryan O'Neal (as an 18th-century Irish adventurer, with a soundtrack by The Chieftains) and Lee Marvin
