In June 1834, Archdale is elected the Member of Parliament for Fermanagh following the retirement of his uncle Mervyn Archdall. He is returned unopposed in the succeeding nine elections. From 1836, he is a noted member of the Orange Order and becomes treasurer of the Grand Lodge of Ireland. He votes in 1856 to disendow Maynooth College. When in 1868 he is asked to support a plea for the reprieve of Michael Barrett, a local Fenian under sentence of death in London, he refuses. He does not stand at the election of January 1874.
On the death of another uncle, Lt. Col. William Archdall, on January 1, 1857, Archdale inherits the family estates of Castle Archdale and Trillick in County Tyrone. He is appointed High Sheriff of Fermanagh in 1879.
Archdale has an interest in and also keeps racehorses. Other pursuits in which he is prominent are coursing and boating. He is a Freemason and member of five clubs.
Archdale marries Emma Inez, the daughter of Jacob Goulding of Kew, Surrey, with whom he has two sons, Mervyn Henry and Hugh James, and three daughters.
Archdale dies on December 22, 1895, at Cannes in the south of France. His estates pass to his brother, William Humphrys Archdale, who also takes over the representation of Fermanagh in Parliament.
Sackville then enters the army. He is elected Grandmaster of the Grand Lodge of Ireland in 1751, serving in this post for two years. He marries Diana Sambrooke, daughter of John Sambrooke and Elizabeth Forester, on September 3, 1754. They have two sons and three daughters.
In 1747 and 1748, Sackville again joins the Duke of Cumberland. He becomes colonel of the 7th Irish horse and serves in Holland. There is a break in his military career between wars (1750-1755) when he serves as first secretary to his father.
In June 1758 Sackville is second in command of a British expedition led by Marlborough which attempts an amphibious Raid on St. Malo. While it fails to take the town as instructed, the raid is still considered to be largely successful as a diversion. Follow-up raids are considered against Le Havre, Caen and other targets in Normandy but no further landings are attempted and the force returns home. Later in 1758 they join the allied forces of Duke Ferdinand of Brunswick in Germany. When Marlborough dies, Sackville becomes Commander of the British contingent of the army, although still under the overall command of the Duke of Brunswick.
In the Battle of Minden on August 1, 1759, British and Hanoverian infantry of the centre make an advance on the French cavalry and artillery in that sector. As the disrupted French begin to fall back on Minden, Ferdinand calls for a British cavalry charge to complete the victory, but Sackville withholds permission for their advance repeatedly. For this action, he is cashiered and sent home. John Manners, Marquess of Granby, replaces him as commander of the British contingent for the remainder of the war.
Sackville refuses to accept responsibility for refusing to obey orders. Back in England, he demands a court-martial, and makes it a large enough issue that he obtains his demand in 1760. The court finds him guilty, and the verdict not only upholds his discharge, but rules that he is “…unfit to serve His Majesty in any military Capacity whatever.” The king has his name struck from the Privy Council rolls.
Sackville is a Member of Parliament at intervals from 1733. He serves terms in both the Dublin and the Westminster bodies, sometimes simultaneously, but does not take sides in political wrangles. Between 1750 and 1755 he serves as Chief Secretary for Ireland, during his father’s second term as Lord Lieutenant of Ireland.
On November 10, 1775, Sackville is appointed Secretary of State for the Colonies replacing William Legge, 2nd Earl of Dartmouth in the post. He becomes a target for the opposition, and is eventually persuaded to step down in exchange for a peerage, and in February 1782 he is made Baron Bolebrooke, in the County of Sussex, and Viscount Sackville, of Drayton in the County of Northamptonshire. His political career ends with the fall of the North government in March 1782.
The controversy over Sackville’s handling of the war continues. Some members are opposed to his taking a seat in the House of Lords, an almost unprecedented incident. In spite of this he is admitted to the Lords, where he is staunchly defended by Edward Thurlow, 1st Baron Thurlow, and his declining health soon makes the issue irrelevant. He retires to his country home at Stoneland Lodge and dies there on August 26, 1785. He maintains to his dying day that he had not been a coward at Minden. Following his death, a defence of his reputation, The character of the late Viscount Sackville, is written by Richard Cumberland.

Wesley is the son of Richard Wesley, 1st Baron Mornington, and Elizabeth Sale. He is educated at Trinity College Dublin and is elected its first Professor of Music in 1764. From early childhood he shows extraordinary talent on the violin and soon begins composing his own works. As a composer he is remembered chiefly for glees such as “Here in cool grot” and for a double Anglican chant. His son, Arthur Wellesley, 1st Duke of Wellington, is the only one of his children to inherit something of his musical talent.
Wesley represents Trim in the Irish House of Commons from 1757 until 1758, when he succeeds his father as 2nd Baron Mornington.
Wesley marries Anne Hill-Trevor, eldest daughter of banker Arthur Hill-Trevor, 1st Viscount Dungannon, and his wife Anne Stafford, on February 6, 1759. His godmother, the famous diarist Mary Delany, says the marriage is happy, despite his lack of financial sense and her “want of judgment.” They have nine children, most of whom are historically significant.
In 1759 Wesley is appointed Custos Rotulorum of Meath and in 1760, in recognition of his musical and philanthropic achievements, he is created Viscount Wellesley, of Dangan Castle in the County of Meath, and Earl of Mornington. He is elected Grandmaster of the Grand Lodge of Ireland in 1776, a post he holds until the following year.
Wesley dies at the age of 45 on May 22, 1781. Like his father, he is careless with money, and his early death leaves the family exposed to financial embarrassment, leading ultimately to the decision to sell all their Irish estates.
Four streets in Camden Town, which form part of the estate of Wesley’s son-in-law Henry FitzRoy, are named Mornington Crescent, Place, Street and Terrace after him. Of these, the first has since become famous as the name of a London Underground station.
