About Edward Southwell, 20th Baron de Clifford

Lived 1738 – 1777 (aged 39). Edward Southwell, 20th Baron de Clifford was a politician.

Edward Southwell, 20th Baron de Clifford (6 June 1738 – 1 November 1777) was a British politician.

Early life

Southwell was born on 6 June 1738 as the only son and heir of Lady Katherine Watson and Edward Southwell Jr. (1705–1755). His father and grandfather had both served as Principal Secretary of State for Ireland. Upon the death of his father in 1755, he inherited the Kings Weston estate near Bristol.

Career Southwell was elected to the British House of Commons as a Whig Member of Parliament for Bridgwater on 28 March 1761, sitting until 1763. On 23 November 1763, he was returned for Gloucestershire, sitting until 1776. He also represented Kinsale in the Irish House of Commons from May 1761 to 1768.

On 17 April 1776, the abeyance of the Barony of Clifford was terminated in his favour, and he entered the British House of Lords as 20th Baron de Clifford.

Edward Southwell, 21st Baron de Clifford (1767–1832), who married on 19 February 1789, at St Anne's Church, Dublin, Mary Elizabeth Bourke, daughter of the Most Rev. Joseph Deane Bourke, 3rd Earl of Mayo and his wife, Elizabeth Meade, sister of John Meade, 1st Earl of Clanwilliam. Diary of the Times of George IV by Lady Charlotte Susan Maria Campbell (page 29) records Lady de Clifford as Governess to Princess Charlotte of Wales. This would be Mary Elizabeth Bourke, who was Lady de Clifford from her marriage in 1789, not her mother-in-law Sophia Campbell, who is generally attributed as Princess Charlotte's governess, but was by then the dowager Lady de Clifford, widow of Edward Southwell, 20th Lord de Clifford, who died in 1777. William Henry Wilkins states in his Mrs. Fitzherbert and George IV (p. 261) that Lady de Clifford was "Sophia, Lady de Clifford married to Edward, 20th Baron de Clifford", but at the time around 1810, Sophia would have been in her mid-sixties and Mary in her early forties, so that Mary seems the likelier candidate to be the Lady de Clifford referred to. Hon. Elizabeth Southwell (1776–1817), who married at St. George’s Church, Hanover Square, London, on 9 April 1792, William Keppel, 4th Earl of Albemarle Hon. Henrietta Southwell, who married Frederick Delmé in 1799 His eldest son, who died with no issue, succeeded him as the 21st Baron de Clifford, and was himself succeeded by the 20th Baron's granddaughter, Sophia Coussmaker (1791–1874), who became the 22nd Baroness de Clifford suo jure after the death of her uncle in 1832. Admiral Hon. Sir Henry Keppel; Reverend Hon. Thomas Robert Keppel, who married Frances Barrett-Lennard (daughter of Sir Thomas Barrett-Lennard, 1st Baronet); Lady Caroline Keppel, who married the Very Reverend Thomas Garnier; and Lady Georgiana Charlotte, who married William Henry Magan.
