Henry Pelham-Clinton, 2nd Duke of Newcastle-under-Lyne

Henry Fiennes Pelham-Clinton, 2nd Duke of Newcastle-under-Lyne, KG, PC (16 April 1720 – 22 February 1794) was born in London, the second son of the 7th Earl of Lincoln.

Henry's father died in 1728, and his brother, the 8th Earl of Lincoln, died in 1730, making Henry the 9th Earl of Lincoln. As he was still a minor, his guardian was his uncle, the 1st Duke of Newcastle-upon-Tyne. Newcastle was childless, and soon regarded Lord Lincoln as his heir. Newcastle, and his brother Henry Pelham, were the two most powerful men in England, and both would serve as Prime Minister. Newcastle controlled political patronage of Parliament and the Crown, and so Lord Lincoln was showered with sinecure posts which brought him a large income. Chief among these sinecures was the lifetime appointment as Controller of Customs for the port of London.

After graduating from university, Lord Lincoln was sent abroad to complete his education. At Turin, Italy, where he was studying fencing, he was joined by his schoolfriend, Horace Walpole. Walpole was in love with Lord Lincoln, and Walpole biographer Timothy Mowl believes the two men were lovers. Lord Lincoln was exceedingly good-looking, and would later have the reputation as the most handsome man in England. While still on his Grand Tour, Walpole and Lord Lincoln quarreled and separated. He returned to England.

On 16 October 1744, Lord Lincoln married his cousin Catherine Pelham (24 July 1727 – 27 July 1760), the daughter of his uncle Henry Pelham, who was at that time prime minister. An agreement was signed whereby Lord Lincoln became the heir of both his uncles, Henry Pelham and the Duke. Through his uncles, Lord Lincoln was also given a place at court, being made a gentleman of the King's Bedchamber. In 1752, he was made a Knight of the Garter.
