Denny, who has recently inherited his father’s seat, has publicly promised to remain neutral between the rival candidates, including Crosbie and Colonel Henry Arthur Herbert. Crosbie believes one of Denny’s comments — whether real or perceived — breaches this neutrality, and he issues a formal challenge.
The confrontation culminates in a duel at Oak Park, Tralee. Crosbie, taking careful aim, shoots Sir Barry Denny through the head, killing him instantly. At the time, killing in such disputes is considered an affair of honour, though legally it is premeditated murder.
The killing shocks the political and social elite of County Kerry. Denny is about to be raised to the Peerage of Ireland as Baron Denmore when he dies. The feud between the Crosbie and Denny families is bitter and long‑lasting, lasting for generations.
Crosbie is returned as MP for Kerry following the by‑election, but he dies suddenly on July 6, 1797 after falling from his horse. Local tradition holds that he was poisoned by the Denny family in revenge for the duel.
This incident remains one of the most notorious episodes in 18th‑century Irish political history, illustrating the intense personal rivalries and honour‑driven violence that often accompanied parliamentary contests in Ireland at the time.
Grattan, a leading Irish WhigMP and a key figure in the Irish Parliament’s push for greater autonomy from Britain, has long advocated for reform of the penal laws that exclude Catholics from political life. His motion seeks to remove the legal barriers preventing Catholics from being elected to Parliament, a move that would significantly alter the balance of power in Ireland.
Although the motion fails, it is part of a broader wave of reformist debate in the late 18th century. Grattan’s efforts lay the groundwork for later Catholic emancipation campaigns, culminating in the Roman Catholic Relief Act of 1829, which finally allows Catholics to sit in Parliament.
The debate is documented in the Report of Debates in the House of Commons of Ireland, session 1796–7, which records Grattan’s motion alongside other contentious issues of the time, such as the suspension of the Habeas Corpus Act and disarming Ulster.
In summary, on October 17, 1796, Henry Grattan’s Catholic emancipation motion is defeated in the Irish House of Commons, underscoring the resistance to Catholic political rights in Ireland at the time, but also marking an early step in the long struggle for reform.
Annesley is a prominent figure in Irish politics during the late 1690s. Initially aligned with the Whig faction, he later moves closer to Tory interests, particularly in his opposition to Catholic influence and the growing presence of ScottishPresbyterians in Ulster. His political stance and actions in the Irish Parliament draw criticism from certain factions.
The “Report of the Commissioners” is a formal parliamentary document produced by a committee tasked with examining Ireland’s governance, economic conditions, and political tensions. Annesley’s involvement in drafting or presenting parts of this report is seen by some as politically damaging or controversial. The exact nature of his contribution is not fully detailed in surviving records, but it is sufficient to trigger his expulsion.
The early 1700s in Ireland are marked by ongoing sectarian tensions between Protestants and Catholics, political maneuvering between Whig and Tory factions in the Irish Parliament and economic hardship and poor governance conditions, which are themes in the commissioners’ report.
Annesley’s expulsion reflects the sensitivity of political discourse in Ireland at the time, where even well-intentioned inquiries can be used to target opponents.
Following his expulsion, Annesley continues his political career in England, being returned as MP for Preston in 1705 and later for Westbury. He remains active in Parliament until 1734, when he does not stand for re-election in the 1734 British general election.
In summary, on September 28, 1703, Francis Annesley is expelled from the Irish House of Commons for his part in the “Report of the Commissioners,” a move that underscores the political risks of engaging in sensitive parliamentary inquiries during a volatile period in Irish history.
Yelverton is the eldest son of Francis Yelverton of Kanturk, County Cork, and Elizabeth Barry, daughter of Jonas Barry of Kilbrin (now Ballyclogh, County Cork). His father dies when he is only ten. His mother reaches a great age, dying only a year before her son. He goes to school in Charleville and Midleton College, and attends Trinity College Dublin, where he takes a degree of Bachelor of Arts in 1757 and of Bachelor of Laws in 1761. His family lacks wealth and social position and he is for some years an assistant master under Andrew Buck in the Hibernian Academy. This menial occupation is later a source of great embarrassment to him, as his enemies love to ridicule him as “Buck’s usher.”
In 1761, Yelverton marries Mary Nugent, daughter of William Nugent of Clonlost, County Westmeath, and his wife Ursula Aglionby, a lady of some fortune, and is thus enabled to read for the Irish Bar, entering the Middle Temple. He is called to the Bar in 1764. Despite his lack of family connections, his success in his profession is rapid, due to his legal ability, charm and remarkable eloquence, and he takes silk eight years afterward.
Yelverton is elected to the Irish House of Commons as member for Donegal Borough from 1774 to 1776. In the latter year, he is elected for both Belfast and Carrickfergus. He chooses to sit for the latter constituency and represents Carrickfergus until 1784. Although few examples of his oratory survive, all contemporaries agree on his eloquence, which gives him a dominant position in the Commons. He also serves as Recorder of Carrickfergus from 1778 until his death. This is not a Crown appointment as the Recorder is elected by a vote of the entire town corporation.
Yelverton gives his support to Henry Grattan and the Whigs during the greater part of his parliamentary career. He is a strong supporter of the demand for an independent Irish Parliament, but later changes his stance.
Yelverton plays a crucial role in the reforms which are collectively called the Irish Constitution of 1782. In particular he sponsors the Act 21 and 22 of George III, An Act to regulate the manner of passing bills and to prevent delays in summoning of Parliaments – which is popularly known as “Yelverton’s Act.” This radically modifies Poynings’ Law of 1495 by which all legislation to be passed by the Irish Parliament has to be drafted by the Privy Council of Ireland, then sent to the English privy council for approval. Under Yelverton’s Act, the role of the Irish Privy Council is abolished and legislation is commenced in the normal way in the Irish Parliament, which for the last 17 years of its existence enjoys a wide measure of independence.
In his latter days, Yelverton becomes identified with the court party and votes for the Act of Union 1800, for which his viscounty is a reward. For this he is never forgiven by many of his former friends. Sir Jonah Barrington, who continues to regard Yelverton with affection and respect, regrets that this action should have destroyed his reputation forever, but he argues that such a mistake of judgment is understandable in a man who lacks worldly wisdom, and despite his many good qualities, does not have a strong moral sense.
Yelverton becomes Attorney-General for Ireland in 1782, and is elevated to the bench as Lord Chief Baron of the Irish Exchequer in 1783. He is created Baron Yelverton in 1795, and in 1800 Viscount Avonmore in the Peerage of Ireland. As Chief Baron, he leads the opposition to the proposal to increase the number of judges in each of the courts of common law from three to four, on the practical ground that four-judge courts often divide evenly and thus cannot reach an effective decision. Despite this common-sense view, the new judges are eventually appointed.
In 1797, Yelverton attains a degree of infamy for presiding over what is widely regarded as a “show trial” which leads to the execution of the United Irishman, William Orr, although he is said to have shed tears when passing the death sentence on Orr. Orr is charged with administering the United Irish oath to a soldier called Hugh Wheatly. This had recently become a capital offence. In fact, it is generally believed that another man, William McKeever, administered the oath. Wheatly, who is the principal witness for the prosecution, later confesses that he had perjured himself, but despite a superb defence by John Philpot Curran, Orr is found guilty and hanged. Yelverton may have formed an early impression of Orr’s guilt and acted on it – even his admirers admitted that as a judge he lacks impartiality.
Peter Finnerty, a journalist, is later convicted of seditious libel for publishing an attack on Yelverton over his conduct of Orr’s trial and this does nothing to enhance the judge’s reputation.
Yelverton dies on August 19, 1805, at his mansion, Fortfield House, Terenure, County Dublin, which he had built at great expense around 1785. He is buried nearby in Rathfarnham.
Hamilton enters Trinity College Dublin on November 17, 1742, at the age of 13 with Thomas McDonnell as his tutor. He graduates Bachelor of Arts (BA) in 1747 and Trinity Master of Arts (MA Dubl) in 1750. He takes the competitive examination for a vacant fellowship of the college in 1750, but the position is secured instead by his friend Richard Murray, who is a few years older. Two fellowships become vacant the following year and Hamilton is elected to one of them at the age of 22. He is appointed Erasmus Smith’s Professor of Natural and Experimental Philosophy at Trinity College Dublin in 1759 and that same year graduates Bachelor of Divinity (BD). He is elected a Fellow of the Royal Society on February 19, 1761, and graduates Doctor of Divinity (DD) in 1762.
Trinity College presents him to the rectory of Kilmacrennan in the diocese of Raphoe, County Donegal, in 1764. This is a small benefice in the gift of the college, for which he resigns his fellowship. He retains the Erasmus Smith’s chair, however, being succeeded in that by Thomas Wilson in 1769. He resigns from Kilmacrenan in 1767 and becomes vicar of St. Ann’s Church in Dublin.
Hamilton then becomes Dean of Armagh, the chief resident cleric of St. Patrick’s Cathedral in Armagh, County Armagh, from April 1768 to 1796. Finding the existing dean’s house inconvenient and poorly situated, he has a new one built in a better location just off Portadown Road, now known as Dean’s Hill. The house, of three stories and a semi-basement, is built in 1772–74. The house is later sold by the church and the present owners provide bed and breakfast accommodation in it. While dean he also acts as treasurer for the infirmary or county hospital, he establishes Sunday schools in the districts of the parish, and he founds a charitable loan for poor tradesmen. He is also instrumental in planning a piped water supply for the town, which is later put into effect. He is one of the 38 original members of the Royal Irish Academy when it is founded in 1785. Gilbert Stuart paints his portrait in about 1790 (pictured above).
Hamilton is promoted to Bishop of Clonfert and Kilmacduagh on January 20, 1796, without seeking it. On January 24, 1799, he is translated to Ossory, where he is bishop until 1805. He dies of a fever at Kilkenny, County Kilkenny, on December 1, 1805. He is buried in the graveyard of St. Canice’s Cathedral at Kilkenny, and there is a memorial to him inside the cathedral.
Hamilton writes a mathematical treatise on conic sections called De Sectionibus Conicis: Tractatus Geometricus, published in 1758. In this book he “was the first to deduce the properties of the conic section from the properties of the cone, by demonstrations which were general, unencumbered by lemmas, and proceeding in a more natural and perspicuous order,” according to writer James Wills in 1847. The work is acclaimed for its lucidity and Leonhard Euler describes it as a perfect book. It is “soon adopted in all the British universities” and is translated from Latin into English as A Geometrical Treatise of the Conic Sections in 1773.
Hamilton also writes Philosophical Essays on Vapours (1767), Four Introductory Lectures on Natural Philosophy (1774), and An Essay on the Existence and Attributes of the Supreme Being (1784). His principal works are collected and republished, with a memoir, as The Works of the Right Rev. Hugh Hamilton by his eldest son, Alexander Hamilton, in two volumes in 1809.
Hamilton marries Isabella, daughter of Hans Widman Wood of Rosmead, County Westmeath, in 1772. Isabella’s mother Frances is the twin sister of Edward King, 1st Earl of Kingston. They have five sons and two daughters. They are Alexander, who was a barrister; Frances; Hans, who is rector of Knocktopher, County Kilkenny, and associated with the Carrickshock incident of 1831; Isabella; Henry; George, who is a biblical scholar; and Hugh, who marries Elizabeth Staples, a daughter of John Staples, a Member of Parliament. The younger Hugh is the great-grandfather of Clive Staples Lewis, better known as C. S. Lewis. Bishop Hugh Hamilton is a great-great-great-grandfather of the mathematicians John Lighton Synge and his brother Edward Hutchinson Synge. Dodgson Hamilton Madden, the High Court judge and noted scholar, is Hamilton’s great-grandson.

Eyre is born around 1720, the second son of Colonel Samuel Eyre of Eyreville, County Galway, a descendant of Colonel John Eyre, who accompanies General Ludlow to Ireland in 1651 and acquires large estates in County Galway, including the Manor of Eyrecourt.
Eyre is that rare man whose military and engineering training occurs entirely in the Americas before he assumes the significant office of Surveyor General of Ireland in 1752. In 1738, he joins the regiment of James Oglethorpe, the founder of the Province of Georgia, and sails to the colony. As a cadet in Oglethorpe’s Regiment, he is sent to the colony’s interior as an agent to the Cherokee Indians. He rises from the rank of cadet to be sub-engineer for Georgia and the Province of South Carolina and in 1740 he is commissioned an ensign. He learns engineering from Major William Cook, the Regiment’s Engineer, and he marries Cook’s daughter Anne, who has accompanied her father to Georgia. The date of the wedding is not documented, but occurs by 1743, by which date both Eyre and Cook have returned to London. In the last two years of his tour of duty, Eyre serves also as the Sub-engineer for South Carolina and Georgia.
In 1744, Eyre is commissioned a lieutenant and joins Trelawney’s Regiment of Foot, headed by Edward Trelawney, Governor of Jamaica. He serves in Jamaica and at Roatán (Rattan) and is in charge of Roatán’s defences until 1748, when the Treaty of Aix-la-Chapelle ends the War of the Austrian Succession and returns the island to Spain. He is promoted to captain in 1748. For the four years after his departure from Roatán and before his resignation from Trelawney’s Regiment, little is known about his activities until he retires from active duty in 1752.
On August 31, 1752, Eyre is appointed Surveyor General of Ireland, having purchased the office from Arthur Jones-Nevill. Joseph Jarratt works as his deputy in this role. He undertakes works at the Royal Barracks in Dublin, but the condition of the barracks is criticised by the Commissioners of the Ordnance for Ireland. As Surveyor General, he is also involved in harbour works at Dún Laoghaire, and is responsible for the rebuilding of the State Apartments at Dublin Castle. In 1763, the office of Surveyor General is abolished, and he is transferred to the new post of Chief Engineer of the Ordnance.
Eyre resigns his commission in 1766 and becomes member of the Irish House of Commons for Thomastown (1761-68) and Fore (1768-1772). He dies on February 22, 1772, from an apoplectic fit brought on by the sudden death of a much loved daughter, at Parliament House, Dublin, while attending a session of the House.
Fitzgibbon is an early and extremely militant opponent of Catholic emancipation. The Earl is possibly the first person to suggest to King George III that granting royal assent to any form of Catholic Emancipation will violate his coronation oath.
FitzGibbon is born in 1748 near Donnybrook, Dublin, the son of John FitzGibbon of Ballysheedy, County Limerick, and his wife Isabella Grove, daughter of John Grove, of Ballyhimmock, County Cork. His father is born a Catholic but converts to the state religion in order to become a lawyer, and amasses a large fortune. He has three sisters, Arabella, Elizabeth, and Eleanor.
When appointed Lord Chancellor for Ireland in 1789, FitzGibbon is granted his first peerage as Baron FitzGibbon, of Connello Lower in County Limerick, in the peerage of Ireland that year. This does not entitle him to a seat in the British House of Lords, only in the Irish House of Lords. His later promotions come mostly in the peerage of Ireland, being advanced to a Viscountcy (1793) and the Earldom of Clare in 1795. He finally achieves a seat in the British House of Lords in 1799 when created Baron FitzGibbon, of Sidbury in the County of Devon, in the Peerage of Great Britain.
FitzGibbon is a renowned champion of the Protestant Ascendancy and an opponent of Catholic emancipation. He despises the Parliament of Ireland‘s popular independent Constitution of 1782. He is also personally and politically opposed to the Irish politician Henry Grattan who urges a moderate course in the Irish Parliament, and is responsible for defeating Grattan’s efforts to reform the Irish land tithe system (1787–1789) under which Irish Catholic farmers (and all non-Anglican farmers) are forced to financially support the minority Anglican Church of Ireland. These are not fully repealed until 1869 when the Church of Ireland is finally disestablished, although Irish tithes are commuted after the Tithe War (1831–1836).
FitzGibbon opposes the Irish Roman Catholic Relief Act 1793, for which, in a “magnificently controlled vituperation in vigorous, colloquial heroic couplets,” The Gibbonade, he is pilloried by the satirist Henrietta Battier. But acceding to pressure exerted through the Irish executive by government of William Pitt in London, intent, in advance of war with the new French Republic, to placate Catholic opinion, he is persuaded to recommend its acceptance in the Irish House of Lords. Pitt, and King George III, who had been petitioned by delegates from the Catholic Committee in Dublin, expects Ireland to follow the British Roman Catholic Relief Act 1791 and admit Catholics to the parliamentary franchise (although not to Parliament itself), enter the professions and assume public office.
FitzGibbon’s role in the recall, soon after his arrival, of the popular pro-Emancipation Lord Lieutenant of Ireland, William Fitzwilliam, 4th Earl Fitzwilliam, is debatable. Although he is probably politically opposed to the Lord Lieutenant of Ireland, Fitzwilliam is recalled, apparently due to his own independent actions. Fitzwilliam is known to be friendly to the Ponsonby family (he is married to one of their daughters), and is generally a Foxite liberal Whig. His close association with and patronage of Irish Whigs led by Grattan and Ponsonby during his short tenure, along with his alleged support of an immediate effort to secure Catholic emancipation in a manner not authorized by the British cabinet is probably what leads to his recall. Thus, if any is to blame in the short-lived “Fitzwilliam episode” it is the great Irish politician Henry Grattan and the Ponsonby brothers – presumably William Ponsonby, later Lord Imokilly, and his brother John Ponsonby—not to mention Lord Fitzwilliam himself. Irish Catholics at the time and later naturally see things very differently and blame hardline Protestants such as FitzGibbon.
Irish Catholics and FitzGibbon agree on one point apparently – Irish political and economic union with Great Britain, which eventually takes place in 1801. Pitt wants Union with Ireland concomitantly with Catholic emancipation, commutation of tithes, and the endowment of the Irish Catholic priesthood. Union is opposed by most hardline Irish Protestants, as well as liberals such as Grattan. FitzGibbon has been a strong supporter of the Union since 1793 but refuses to have Catholic emancipation with the Union.
In a speech to the Irish House of Lords on February 10, 1800, FitzGibbon elucidates his point of view on union: “I hope and feel as becomes a true Irishman, for the dignity and independence of my country, and therefore I would elevate her to her proper station, in the rank of civilised nations. I wish to advance her from the degraded post of mercenary province, to the proud station of an integral and governing member of the greatest empire in the world.”
In the end, FitzGibbon’s views win out, leading to the Union of Ireland with Great Britain to form the United Kingdom of Great Britain and Ireland without any concessions for Ireland’s Catholic majority (or for that matter, Catholics in the rest of the new United Kingdom). He later claims that he had been duped by the way in which the Act was passed with the new Viceroy Charles Cornwallis, 1st Marquess Cornwallis, promising reforms to Irish Catholics, and is bitterly opposed to any concessions during the short remainder of his life.
The role of the Earl of Clare (as FitzGibbon becomes in 1795) as Lord Chancellor of Ireland during the period of the Irish Rebellion of 1798 is questionable. According to some, he supports a hardline policy which uses torture, murder and massacre to crush the rebellion, or that as Lord Chancellor, he has considerable influence on military affairs, and that martial law cannot be imposed without his consent. Others allege that as Lord Chancellor, he has no say in military affairs and the Encyclopædia Britannica states that he is “neither cruel nor immoderate and was inclined to mercy when dealing with individuals.” However, the same source also states that “(FitzGibbon)… was a powerful supporter of a repressive policy toward Irish Catholics”. His former side is displayed by sparing the lives of the captured United Irish leaders, “State prisoners,” in return for their confession of complicity and provision of information relating to the planning of the rebellion. However, this willingness of the prisoners to partake of the agreement is spurred by the execution of the brothers John and Henry Sheares on July 14, 1798.
In contrast to the leniency shown to the largely upper-class leadership, the full weight of military repression is inflicted upon the common people throughout the years 1797–98 with untold thousands suffering imprisonment, torture, transportation and death. FitzGibbon is inclined to show no mercy to unrepentant rebels and, in October 1798, he expresses his disgust upon the capture of Wolfe Tone that he has been granted a trial, and his belief that Tone should be hanged as soon as he set foot on land.
FitzGibbon is quick to recognise that sectarianism is a useful ally to divide the rebels and prevent the United Irishmen from achieving their goal of uniting Protestant, Catholic and Dissenter, writing in June 1798, “In the North nothing will keep the rebels quiet but the conviction that where treason has broken out the rebellion is merely popish.”
Another anecdote is to the effect of FitzGibbon’s callousness. Supposedly, upon being informed during a debate in the Irish Parliament that innocent as well as guilty are suffering atrocities during the repression, he replies, “Well suppose it were so…,” his callous reply purportedly shocking William Pitt.
FitzGibbon is noted by some as a good, improving landlord to both his Protestant and Catholic tenants. Some claim that the tenants of his Mountshannon estate call him “Black Jack” FitzGibbon. There is, however, no evidence to support this claim, although there is little to no evidence on his dealings as a landlord. Irish nationalists and others point out that while he might be interested in the welfare of his own tenants on his own estate, he treats other Irish Catholics very differently. Without further evidence, his role as a Protestant landowner in mainly Catholic Ireland is of little importance against his known dealings as Lord Chancellor.
FitzGibbon dies at home, 6 Ely Place near St. Stephen’s Green, Dublin, on January 28, 1802, and is buried in St. Peter’s Churchyard. A hero to Protestant hardliners, but despised by the majority Catholic population, his funeral cortege is the cause of a riot and, according to a widespread story, a number of dead cats are thrown at his coffin as it departs Ely Place.
Alongside his older brother, Connor Maguire, Maguire is a prime mover in the conspiracy which leads to the outbreak of rebellion in Ireland on October 23, 1641. He is tasked with securing County Fermanagh for the rebels, but is only partially successful, with several key fortresses in the county, including Enniskillen Castle, remaining under Protestant settler control. His attempt to murder Sir William Cole immediately prior to the rising fails, but the landowner Arthur Champion is killed in one of the first actions of the rebellion. In November 1641, he joins Felim O’Neill of Kinard at Newry to issue a proclamation in which the rebels claim they are acting in defence of King Charles and Catholicism. In December 1641, the Fermanagh army under Maguire slaughters many of the garrison and refugees in Tully Castle, apparently in retaliation for the killing of the garrison of a Maguire castle which had been taken by assault some days previously. He also destroys Castle Archdale and its neighbouring settler village, and kills eight Protestant settlers at Monea Castle. In early 1642, he is expelled from the Irish Parliament and in the summer of the same year he is made a colonel in Owen Roe O’Neill‘s army in Ulster.
Maguire is appointed Governor of Fermanagh by the authorities of the newly established Confederate Ireland. He commands the rebel reserve in the Battle of Benburb in June 1646. He leads raids into Protestant-held areas in east Ulster, before joining O’Neill in his campaigns in Leinster in the autumn of 1646. Later that year, he raids lands in Connacht controlled by the Royalist commander, Ulick Burke, 1st Marquess of Clanricarde. In August 1647, O’Neill and Maguire move the army to Leinster, where Maguire quarrels so vigorously with O’Neill over the payment of troops that the general orders his arrest and court-martials him. After the court-martial, Maguire and his supporters, about five or six regiments, draw up their forces and threaten to desert. The mutiny soon dissipates and Maguire remains allied to O’Neill.
In 1648, Maguire joins O’Neill in opposing the truce between the Confederates and Royalists. He plays a prominent role in the skirmishes and evasive manoeuvrings that occur between the two sides in central Ireland. In the winter of 1648, Maguire withdraws north and on November 13 he is killed while leading an attack on a fortress near Jamestown, County Leitrim.
FitzGerald is born on March 13, 1749, in Arlington Place, Piccadilly, London, the second son of nine sons and ten daughters of James Fitzgerald, 20th Earl of Kildare and later 1st Duke of Leinster, and his wife, Lady Emily Lennox. He is educated at Eton College (1758–63). He is the elder brother of the 1790s revolutionary Lord Edward FitzGerald, and is a first cousin of the English liberal politician Charles James Fox.
In November 1775, FitzGerald marries Emilia Olivia Usher, daughter of the 1st Baron Saint George and Elizabeth Dominick and sole grand daughter of Sir Christopher Dominick. They have three sons and six daughters.
In 1770, FitzGerald is chosen Grandmaster of the masonicGrand Lodge of Ireland, a post he holds for two years. He is re-elected for another year in 1777. In 1783, he is among the first knights in the newly created Order of St. Patrick.
In 1788–89, FitzGerald is Master of the Rolls in Ireland. In theory a senior judicial office, it is then largely a sinecure, but so blatant a choice of a man who is wholly unqualified for it gives rise to unfavourable comment, and a few years later it becomes the rule that the Master must be a lawyer of repute.
FitzGerald’s homes are at Carton and Kilkea Castle in County Kildare, and at Leinster House in Dublin (now the home of the Oireachtas). He is a founder member of the Order of St. Patrick in 1783 and of the Royal Irish Academy in 1785, and is a large investor in the Royal Canal company launched in 1790. His family’s estates of 60,000 acres (25,000 Ha) in Kildare are in three main parts, around Maynooth, Rathangan and Athy. He rebuilds the main bridge in Athy over the River Barrow.
FitzGerald dies of strangury, a urinary tract disorder, at Carton House on October 20, 1804. He is buried in Kildare Abbey. His funeral is so well attended that the mourners reach across The Curragh. He is succeeded by his second, but eldest surviving, son, Augustus Frederick Fitzgerald, as 3rd Duke of Leinster.
FitzGerald marries Charlotte Boyle Walsingham in London on August 3, 1791. Together they live at Boyle Farm, Thames Ditton. In 1806, his wife succeeds to the Baron de Ros, the premier baron in the Peerage of England, as 20th Baroness de Ros. The family then takes the surname FitzGerald-de Ros. The couple has 13 children in 21 years, of which nine survive to adulthood.
