George Greville, 2nd Earl of Warwick

[3] Another recorded tutor was William Patoun, an amateur artist as well as librarian of Glasgow University who produced a portrait of the future Earl that survives at Warwick Castle.

From Scotland he returned so well informed, and such an amiable manliness about him, that the most flattering prognostications were made of his future eminence... His travels did not in any great degree either improve or corrupt him, and he has since remained a quiet inoffensive domestic character, little known but by persons of taste and virtue.

They had four children: On 6 July 1773, Greville inherited his father's title of Earl of Warwick and left the House of Commons.

The Biographical Index to the House of Lords records that "this peer has evinced a predominant taste for chymistry, and if we mistake not greatly, a patent for soap for the navy that will not curdle in salt water was taken out in his name.

However, it has only recently been understood that Greville's wife, Henrietta Vernon, was the half sister of John FitzPatrick, Lord Gowran (later 2nd Earl of Upper Ossory) via the first Marriage of her Mother (Lady Evelyn Leveson-Gower), and a cousin of Lord Sedley (later Venables-Vernon) via her father Richard Vernon.

Therefore, Higton's portraits of Warwick Castle, combined with those of Dogs belonging to George Greville, Lord Sedley, and John Fitzpatrick, perhaps reflect a more intimate relationship with the family, and their circle, than was understood.

Although Greville had commissioned Romney to purchase paintings on his behalf in Italy, lack of pictures of quality meant that he returned empty handed.
