Sir Charles Herbert Sheffield, 1st Baronet
Sir Charles Herbert Sheffield, 1st Baronet (c. 1706–1774) of Normanby, Lincolnshire, England, was an illegitimate son of John Sheffield, 1st Duke of Buckingham and Normanby and the first of the Sheffield baronets, and the owner of Buckingham Palace (then known as Buckingham House) who sold it to King George III.
Sheffield, baptised Charles Herbert, was illegitimate son of John Sheffield, 1st Duke of Buckingham and Normanby and Frances Stewart, who, then or afterwards, was the wife of The Hon. Oliver Lambart, younger son of Charles Lambart, 3rd Earl of Cavan.
Sheffield was probably born about 1706 (when his mother was 22 years old, was "under the tuition of Mons. Brezy, at Utretcht", in August 1716, and took the name of Sheffield, instead of Herbert. He inherited, on the death, 30 October 1735, of the 2nd and last Duke (at his age of 19), the considerable estates of both of these Dukes, in Lincolnshire and elsewhere. He was created a baronet on 1 March 1755. He died 5 September 1774.
On 25 April 1741, Sheffield married Margaret Diana, daughter of General Joseph Sabine, sometime Governor of Ghent and Gibraltar. She died 7 January 1762, in Buckingham House, St James's Park, which shortly afterwards was sold by her husband for £21,000 to King George III.
- She is called in Playfair's Baronetage (1811), "S, C, Stewart, afterwards Mrs. Lambert." Her christian name, however, was undoubtedly Frances (Cokayne 1906, p. 102).
- Cokayne 1906, p. 102.
- See Col, Chester's note to her burial, 11 Jan. 1750/1, aged 66, in his Registers of Westminster Abbey (Cokayne 1906, p. 102).
- Under the will of John Sheffield, dated 2 August 1716, and probated 28 March 1721 (Cokayne 1906, p. 102).
- It is just possible that the matriculated at Oxford (Ch. Ch.) 5 September 1721 of "Charles Herbert, son of John, of Westminster, Esq., [sic] aged 18," may refer to him (Cokayne 1906, p. 102).
- Will of Charles Sheffield probated July 1775 (Cokayne 1906, p. 102).
