Thomas Noel, 2nd Viscount Wentworth

Thomas Noel, 2nd Viscount Wentworth (18 November 1745 – 17 April 1815) was a British politician who succeeded to a peerage before he could take his seat in the House of Commons, having just been elected in 1774.

Wentworth was the only son of Edward Noel, 1st Viscount Wentworth and his wife, Judith Lamb, daughter of William Lamb of Wellesborough, Leicestershire. He was educated at Eton and, having matriculated at Brasenose College, Oxford on 4 November 1763, was awarded MA on 29 April 1766.

At the 1774 general election, Noel successfully contested Leicestershire and was returned as Member of Parliament. However, he had to leave the Commons within a month when he succeeded to the peerage on the death of his father on 31 October.

On 2 February 1788, Wentworth married Mary, Dowager Countess Ligonier, a daughter of the 1st Earl of Northington and widow of the 1st Earl Ligonier of the second creation. The union did not produce any children, although Wentworth had fathered an illegitimate son, Thomas Noel (1774–1853), who became rector of Kirkby Mallory. There he conducted the marriage ceremony of his cousin, Anne Isabella, to Lord Byron in 1815.

Upon his death in 1815, Lord Wentworth's viscountcy became extinct, whilst the barony of Wentworth became abeyant between his nephew Hon. Nathaniel Curzon (later Lord Curzon) and his sister, Judith and her daughter Anne. When Judith died in 1822 and then Lord Curzon died without heirs in 1856, the abeyancy was terminated in favour of Anne.
