Duke of Leinster


Duke of Leinster is a title that has been created twice in the Peerage of Ireland since 1691. It does not include any territorial landholdings and does not produce any revenue for the title-holder.
Currently Duke of Leinster is the premier dukedom in the Peerage of Ireland. The subsidiary titles of the Duke of Leinster are Marquess of Kildare, Earl of Kildare, Earl of Offaly, Viscount Leinster, of Taplow in the County of Buckingham, Baron of Offaly, Baron Offaly and Baron Kildare, of Kildare in the County of Kildare. The viscounty of Leinster is in the Peerage of Great Britain, the barony of Kildare in the Peerage of the United Kingdom, and all other titles in the Peerage of Ireland. The courtesy title of the eldest son and heir of the Duke of Leinster is Marquess of Kildare. The Duke of Leinster is the head of the House of Kildare.

Duke of Leinster, first creation (1691)

The title was first conferred on General Meinhardt Schomberg, later the 3rd Duke of Schomberg, K.G. in 1691. Schomberg was created Duke of Leinster for his part in the Battle on 30 June 1690 and, after taking part in the abortive Siege of Limerick in August 1690, he became a British subject through naturalization by Act of Parliament on 25 April 1691. However, that creation became extinct upon Schomberg's death in July 1719.

    Dukes of Leinster, second creation (1766)

For the second creation, it was granted to Major-General James FitzGerald, 1st Marquess of Kildare, Master-General of the Irish Ordnance, in 1766. FitzGerald married to Lady Emily Lennox, the great-granddaughter of King Charles II of the Royal House of Stuart.

Earls of Kildare from 1316

This branch of the Cambro Norman FitzGerald/FitzMaurice dynasty, which came to Ireland in 1169, were initially created Earls of Kildare. The earldom was created in 1316 for John FitzGerald. Two senior FitzGeralds, Garret Mór FitzGerald and his son, Garret Óg FitzGerald served as Lords Deputy of Ireland, the representative of the Lord of Ireland in Ireland. The tenth earl, Thomas FitzGerald, known as Silken Thomas, was attainted and his honours were forfeit in 1537. In 1554, Thomas's half-brother and only male heir, Gerald FitzGerald, was created Earl of Kildare in the Peerage of Ireland. He was subsequently restored to the original letters patent in 1569, as 11th earl. The second earldom became extinct in 1599, although the original earldom survived.

Dukes of Leinster from 1766

The family was originally based in Maynooth Castle in Maynooth in County Kildare. In later centuries the family owned estates in County Waterford with their country residence being a Georgian house called Carton House which had replaced the castle in County Kildare. In Dublin, the Earl built a large townhouse residence on the southside of Dublin called Kildare House. When the Earl was awarded a dukedom and became Duke of Leinster, the house was renamed Leinster House. One of its occupants was Lord Edward FitzGerald, who became an icon for Irish nationalism through his involvement with the Irish Rebellion of 1798, which ultimately cost him his life.
Leinster House was sold by the Leinsters in 1815. After nearly a century as the headquarters of the Royal Dublin Society, which held its famed Spring Show and Horse Show in its grounds, Oireachtas Éireann, the two chamber parliament of the new Irish Free State, rented Leinster House in 1922 to be its temporary parliament house. In 1924 it bought the building for parliamentary use. It has remained the parliament house of the Irish state.
The Dukes of Leinster had by the early 20th century lost all their property and wealth. Their Carton House seat was sold, as later on was their other residence in Waterford. The family now live in a smaller property in Ramsden, Oxfordshire.

Title dispute

A controversial claim by claimants who say they are descended from Gerald FitzGerald, 5th Duke of Leinster, which is reported to have been largely debunked by Michael Estorick in 1981, was made in 2006 and subsequently failed.
In 2005, a claim was filed with the Department of Constitutional Affairs by Theresa Pamella Caudill, daughter of Eleanor and Maurice F. "Desmond" FitzGerald, on behalf of her nephew, a California builder, Paul FitzGerald, as claimant to be the rightful Duke of Leinster. FitzGerald was claimed to be the grandson of Major Lord Desmond FitzGerald, the second son of the 5th Duke of Leinster, who was recorded as having been killed in action during the First World War, while serving with the Irish Guards. When Maurice, 6th Duke of Leinster, died childless, in February 1922, the Leinster dukedom and its considerable wealth and estates devolved upon his youngest brother, Lord Edward FitzGerald, who succeeded as the 7th Duke. However, Paul FitzGerald's supporters claimed that Lord Desmond had faked his death and emigrated to California, by way of Winnipeg, Canada, where he lived until his death in 1967. It was further claimed by Mrs Caudill that a package of documents, witnessed by Edward, Prince of Wales, Sir Edgar Vincent, and Lord Feversham, had been lodged by her father with the Crown Office of the House of Lords in 1929, and the family had been denied access to them. Mrs Caudill believed the documents included evidence that her father had agreed to relinquish the title for his own generation but had insisted that it was to be passed down to his son, her brother Leonard FitzGerald. Instead, it had remained in the family of the 7th Duke. She claimed that an archivist had acknowledged the package existed, but said the official line was that it was now lost.
In February 2006, Lord Falconer of Thoroton, Lord Chancellor, and Harriet Harman, Minister of State in the Department for Constitutional Affairs, considered this claim after a 30-year campaign by Paul FitzGerald's family reported to have cost £1.3 million, and dismissed it. They adjudicated that the title was to remain with the existing holder, Maurice FitzGerald. Paul FitzGerald had a right of appeal against the Lord Chancellor's verdict only by petitioning the monarch.
In 2010, DNA evidence was presented that indicated that Paul FitzGerald was related to the wife of the 5th Duke, the former Lady Hermione Duncombe. As reported in The Scotsman,

With the help of Dunfermline-based genealogist Lloyd Pitcairn, Mrs FitzGerald Caudill traced Maud Crawford, the grand-daughter of Lady Hermione's younger sister Urica Duncombe.
The results of the tests found that it was "41 times more probable" that Ms Crawford and Paul FitzGerald were extremely closely related than that they were from different families. The proof that Paul FitzGerald is related to the ducal family is the first DNA evidence produced in the case, and it supports Mrs Fitz-Gerald Caudhill's claim that her mysterious father was the son of Lady Hermione, the wife of the fifth Duke of Leinster.

Theresa Pamella Caudill died on July 25, 2015.
It had also previously been alleged that Edward FitzGerald, who succeeded as 7th Duke, was the biological son of the 11th Earl of Wemyss. Were this to be established, then neither the present Duke nor any other descendant of his grandfather, the 7th Duke, would be a legitimate heir of the 1st Duke of Leinster.
