James Stuart-Wortley, 1st Baron Wharncliffe

Colonel James Archibald Stuart-Wortley-Mackenzie, 1st Baron Wharncliffe, PC (6 October 1776 – 19 December 1845), was a British soldier and politician. A grandson of Prime Minister the 3rd Earl of Bute, he held office under Sir Robert Peel as Lord Privy Seal between 1834 and 1835 and as Lord President of the Council between 1841 and 1845.

Background and education Stuart-Wortley was the son of Colonel James Stuart-Wortley-Mackenzie, son of John Stuart, 3rd Earl of Bute, and his wife Mary Wortley-Montagu, Baroness Mountstuart in her own right, daughter of Edward Wortley Montagu and Lady Mary Pierrepont. His father had assumed the additional surname of Wortley as heir to his mother, taking later also that of Mackenzie (which his son in later life discarded) as heir to his great-uncle James Stuart-Mackenzie of Rosehaugh. Stuart-Wortley's mother was Margaret, daughter of Lieutenant-General Sir David Cunynghame, 3rd Baronet. He was educated at Charterhouse School.

His attitude on various questions became gradually more liberal, and his support of Catholic Emancipation lost him his seat in 1826. He was then raised to the peerage as Baron Wharncliffe, of Wortley in the County of York, a recognition both of his previous parliamentary activity and of his high position among the country gentlemen.

He at first opposed the 1832 Reform Bill but, having come to see the undesirability of a popular conflict, separated himself from the Tories (with a number of colleagues, collectively known as "the Waverers") and took an important part in modifying the attitude of the peers and helping to pass the bill, though his attempts at amendment only resulted in his pleasing neither party. He became Lord Privy Seal in Sir Robert Peel's short 1834 to 1835 ministry, and again joined him in 1841 as Lord President of the Council,

In 1837 Lord Wharncliffe brought out an edition of the writings of his ancestress, Lady Mary Wortley Montagu.

Family The future Lord Wharncliffe married Lady Elizabeth Caroline Mary Creighton (1779–1856), daughter of the 1st Earl Erne and his second wife Lady Mary Hervey, on 30 March 1799. They had five children:

John Stuart-Wortley-Mackenzie, 2nd Baron Wharncliffe (1801–1855) Hon. Charles Stuart-Wortley-Mackenzie (1802–1844) Hon. Caroline Mary Stuart-Wortley (1803–1806) Hon. James Archibald Stuart-Wortley (1805–1881), Solicitor-General Hon. Caroline Jane Stuart-Wortley-Mackenzie (1809–12 June 1876), married on 30 August 1830 Hon. John Chetwynd-Talbot (1806–1852)

Lord Wharncliffe died in December 1845, aged 69, and was succeeded in the barony by his eldest son, John, whose son Edward, 3rd Baron Wharncliffe, was created Earl of Wharncliffe in 1876. Lady Wharncliffe died in April 1856.
