Personal life, family and death
Eliott was a teetotaller and vegetarian. It was recorded that he "never touched strong liquor or meat, but lived chiefly on vegetables, simple puddings, and water". He did not sleep for more than four hours at a time.
On 8 September 1748 at St Sepulchre-without-Newgate, London, George Augustus Eliott married Anne Pollexfen Drake (1726–1772), the sister of Sir Francis Drake, 5th Baronet (1723–1794) of Nutwell House, Woodbury in Devon, a collateral descendant of Sir Francis Drake. They had two children:
Francis Augustus Eliott, 2nd Baron Heathfield (31 December 1750 – 26 January 1813), who never married, had no offspring and was therefore the last Baron Heathfield. He inherited Nutwell from his uncle Sir Francis Drake, 5th Baronet (1723–1794);
Anne Pollexfen Eliott (1754-24 February 1835), who married John Trayton Fuller on 21 May 1777 with numerous children.
On 6 July 1790, Eliott died at the Schloss Kalkofen, Aachen, of palsy / stroke, allegedly brought on by drinking too much of the local mineral water, and was initially buried in the grounds of the Schloss. His personal estate was probated by 27 July and his furniture sold off by his heirs. Later in 1790, his body was disinterred and reburied at Heathfield, East Sussex. Later still, his body was again disinterred and reburied at St Andrew's Church, Buckland Monachorum, Devon in the church associated with his wife's Drake ancestry.
