Question: Who's son concluded a set of treaties which ended the American Revolutionary War?

full_context: Document 1: Treaty of Hubertusburg: The Treaty of Hubertusburg (German: "Frieden von Hubertusburg" ) was signed on 15 February 1763 at Hubertusburg Castle by Prussia, Austria and Saxony to end the Third Silesian War. Together with the Treaty of Paris, signed five days earlier, it marked the end of the Seven Years' War. The treaty ended the continental conflict with no significant changes in prewar borders. Austria and Saxony renounced all claims to the Silesian territories ceded to Prussia in the 1742 Treaty of Berlin and the 1745 Treaty of Dresden. Prussia clearly stood among the ranks of the European great powers, while the treaty enhanced the rivalry with Austria.
Document 2: John Manners, 3rd Duke of Rutland: John Manners, 3rd Duke of Rutland KG PC (21 October 1696 – 29 May 1779) was an English nobleman, the eldest son of John Manners, 2nd Duke of Rutland and Catherine Russell. Styled Marquess of Granby from 1711, he succeeded to the title in 1721, cutting short a brief career in the House of Commons, where he had represented Rutland as a Whig.

Document 4: Charles Cornwallis, 1st Marquess Cornwallis: Charles Cornwallis, 1st Marquess Cornwallis KG, PC (31 December 1738 – 5 October 1805), styled Viscount Brome between 1753 and 1762 and known as The Earl Cornwallis between 1762 and 1792, was a British Army officer and colonial administrator. In the United States and the United Kingdom he is best remembered as one of the leading British generals in the American War of Independence. His surrender in 1781 to a combined American and French force at the Siege of Yorktown ended significant hostilities in North America. He also served as a civil and military governor in Ireland and India; in both places he brought about significant changes, including the Act of Union in Ireland, and the Cornwallis Code and the Permanent Settlement in India.

The first creation came in the Peerage of Great Britain on 10 September 1766 in favour of the French-born soldier Field Marshal John Ligonier. The peerage was created with normal remainder to the heirs male of his body. He had already been created Viscount Ligonier, of Enniskillen, in the Peerage of Ireland on 31 December 1757, with normal remainder to the heirs male of his body, and Viscount Ligonier, of Clonmell, in the Peerage of Ireland on 20 May 1762, with remainder to his nephew, Edward Ligonier.

It established peace between France and the United Kingdom of Great Britain and Ireland, Russia, Austria, and Prussia, who in March had defined their common war aim in Chaumont. The Treaty was also signed by Portugal and Sweden while Spain signed shortly after in July. Peace talks had started on 9 May between Talleyrand, who negotiated with the allies of Chaumont on behalf of the exiled Bourbon king Louis XVIII of France. The allies had agreed to reduce France to her 1792 borders and restore the independence of her neighbors after Napoleon Bonaparte's defeat. However, the allied parties did not sign a common document, but instead concluded separate treaties with France allowing for specific amendments.
Document 9: Baron Feversham: Baron Feversham is a title that has been created twice, once in the Peerage of Great Britain and once in the Peerage of the United Kingdom. The first creation, in the Peerage of Great Britain, came in 1747 when Anthony Duncombe, who had earlier represented Salisbury and Downton in the House of Commons, was made Lord Feversham, Baron of Downton, in the County of Wilts. He had previously inherited half of the enormous fortune of his uncle Sir Charles Duncombe. However, Lord Feversham had no sons and the barony became extinct on his death in 1763. The peerage was revived in the Peerage of the United Kingdom in 1826 in favour of his kinsman Charles Duncombe, who was created Baron Feversham, of Duncombe Park in the County of York. He was a former Member of Parliament for Shaftesbury, Aldborough, Heytesbury and Newport. Duncombe was the grandson of Thomas Duncombe, son of John Brown (who assumed the surname Duncombe) by his wife Ursula Duncombe, aunt of the first Baron of the 1747 creation.

Document 10: Treaty of Ghent: The Treaty of Ghent (8 Stat. 218 ) was the peace treaty that ended the War of 1812 between the United States of America and the United Kingdom of Great Britain and Ireland. Both sides signed it on December 24, 1814, in the city of Ghent, Belgium. The treaty restored relations between the two nations to "status quo ante bellum", restoring the borders of the two countries to the lines before the war started in June 1812. The Treaty was approved by the UK parliament and signed into law by the Prince Regent (the future King George IV) on December 30, 1814. It took a month for news of the peace treaty to reach the United States, and in the meantime American forces under Andrew Jackson won the Battle of New Orleans on January 8, 1815. The Treaty of Ghent was not fully in effect until it was ratified by the U.S. Senate unanimously on February 17, 1815. It began two centuries of peaceful relations between the U.S. and Britain, although there were a few tense moments such as the Trent Affair.
Document 11: Truce of Ratisbon: The Truce of Ratisbon, or Truce of Regensburg, concluded the War of the Reunions between Spain and France. The Truce was signed on 15 August 1684 at the Dominican convent at Ratisbon in Bavaria between Louis XIV of France on the one side, and the Holy Roman Emperor, Leopold I, and the Spanish King, Charles II, on the other. The final agreements allowed King Louis to retain Strasbourg, Luxembourg, and other Reunion gains, and Kortrijk and Diksmuide, both now in Belgium, were returned to Spain. It was not, however, a definitive peace but only a truce for 20 years.
Document 12: Anglo-French War (1778–1783): The Anglo-French War was a military conflict fought between France and Great Britain with their respective allies between 1778 and 1783. In 1778, France signed a treaty of friendship with the United States. Great Britain was then at war with France, and in 1779 it was also at war with Spain. As a consequence, Great Britain was forced to divert resources used to fight the war in North America to theatres in Europe, India and the West Indies, and to rely on what turned out to be the chimera of Loyalist support in its North American operations. From 1778 to 1783, with or without their allies, France and Britain fought over dominance in the English Channel, the Mediterranean, the Indian Ocean and the West Indies.
Document 13: Treaty of Alliance (1778): The Treaty of Alliance with France or Franco-American Treaty was a defensive alliance between France and the United States of America, formed in the midst of the American Revolutionary War, which promised mutual military support in case fighting should break out between French and British forces, as the result signing the previously concluded Treaty of Amity and Commerce. The alliance was planned to endure indefinitely into the future. Delegates of King Louis XVI of France and the Second Continental Congress, who represented the United States at this time, signed the two treaties along with a separate and secret clause dealing with future Spanish involvement, at the hôtel de Coislin (4, place de la Concorde) in Paris on February 6, 1778. The Franco-American alliance that would technically remain in effect until the 1800 Treaty of Mortefontaine, despite being annulled by the United States Congress in 1793 when George Washington gave his Neutrality Proclamation speech saying that America would stay neutral in the French Revolution.
Document 14: Baron Carteret: Baron Carteret is a title that has been created twice in British history, once in the Peerage of England and once in the Peerage of Great Britain. The first creation came into the Peerage of England in 1681 when the fourteen-year-old Sir George Carteret, 2nd Baronet, was made Baron Carteret, of Hawnes in the County of Bedford (now Haynes Park). The peerage was originally proposed for his grandfather Sir George Carteret, 1st Baronet, a celebrated royalist statesman, but he died before he was granted the title and as his eldest son, Philip, predeceased him, it was eventually bestowed on his grandson, George, with remainder to the latter's brothers. The Baronetcy, of Metesches in the Island of Jersey, had been created for George Carteret in the Baronetage of England on 9 May 1645. Lord Carteret married Lady Grace Granville, daughter of John Granville, 1st Earl of Bath. In 1715 Lady Grace was raised to the Peerage of Great Britain in her own right as Viscountess Carteret and Countess Granville (see Earl Granville for a more details on these two peerages). Lord Carteret and Lady Granville were both succeeded by their son John Carteret, the second Baron and second Earl. The titles became extinct on the death of the latter's son Robert Carteret, the third Earl, in 1776.
Document 15: Charles Townshend, 2nd Viscount Townshend: Charles Townshend, 2nd Viscount Townshend, ( ; 18 April 167421 June 1738) was an English Whig statesman. He served for a decade as Secretary of State for the Northern Department, 1714-1717, 1731-1730. He directed British foreign policy in close collaboration with his brother-in-law, prime minister Robert Walpole. He was often known as Turnip Townshend because of his strong interest in farming turnips and his role in the British Agricultural Revolution.
