Sir Charles Sheffield, 1st Baronet

Sir Charles Herbert Sheffield, 1st Baronet (c. 1706 – 5 September 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. Biography Sheffield, baptised Charles Herbert, was an 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 by a private act of Parliament, (9 Geo. 2. c. 20 ), 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.

Family On 25 April 1741, Sheffield married Margaret Diana, daughter of General Joseph Sabine, sometime Governor of Ghent and Gibraltar. She died on 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.

In today's money (2023) the property was sold for £5,523,960.36.
