Henry Grey, 1st Duke of Kent, KG, PC (16715 June 1740) was a British politician and courtier. None of his sons outlived him, so his new title became extinct on his death. Though the house he built at Wrest Park in Bedfordshire has gone, parts of his very grand garden have survived relatively untouched.
He was a son of Anthony Grey, 11th Earl of Kent, and Mary Grey, 1st Baroness Lucas of Crudwell. He succeeded his father as 12th Earl of Kent in 1702, having succeeded his mother as 2nd Baron Lucas earlier the same year. He was the grandfather, through his daughter Anne Grey, of Henry Cavendish, the preeminent English chemist and physicist of the late 18th century.
Having taken his seat in the House of Lords and though regarded as lacking talent and ambition[1] he, as the politically expedient candidate, was made Lord Chamberlain and a Privy Councillor in 1704. Grey was unpopular; he was nicknamed 'Bug' for his body odour.[2] He traded his position for a dukedom in 1710, and was succeeded as Lord Chamberlain by the Duke of Shrewsbury. Contemporary commentators including John Macky and Jonathan Swift did defend Grey. He might have been, for his time, the right man in the right place.[1]
After 1710 he served in politically minor positions: Gentleman of the Bedchamber, Constable of Windsor Castle, Lord Steward of the Household from 1716 until 1718, and Lord Keeper of the Privy Seal from 1719 until 1720. He was one of the Lords Justices appointed during the absence of George I of Great Britain.
In 1719, Grey was one of the main subscribers in the eighteenth-century Royal Academy of Music, a corporation that produced baroque opera on stage. At the age of 68, a year before his death, he took part, as a founding governor, in the creation of Britain's first home for abandoned children, London's Foundling Hospital.
Grey succeeded his father as 12th Earl of Kent in 1702, having succeeded his mother as 2nd Baron Lucas earlier the same year. He was created Marquess of Kent, Earl of Harold and Viscount Goderich in 1706, Duke of Kent in 1710 for relinquishing his Lord Chamberlain position, and made a Knight of the Garter in 1712. Left without a male heir after the death of his son George Grey, Earl of Harold, in 1733, he was created Marquess Grey in 1740, with a special remainder to his granddaughter Lady Jemima Campbell and her heirs male. She also succeeded to the Barony of Lucas. All his other titles became extinct at his death.
Henry married firstly, in 1694, Jemima Crew (died 2 July 1728), a daughter of Thomas Crew, 2nd Baron Crew, and his second wife, Anne Armine, daughter of Sir William Armine, 2nd Baronet.[3] They had at least six children:
He married secondly Sophia Bentinck (died 5 June 1741) on 24 March 1729, a daughter of William Bentinck, 1st Earl of Portland, and his second wife Jane Martha Temple. They had a son and a daughter:
