The 'Miss Finch' referred to on the miniature's reverse is Charlotte, Lady Charlotte's eldest daughter, who died of consumption in 1767 and was always referred to by her brothers and sisters as 'Miss Finch'. Lady Charlotte (1725-1813), who was governess to the children of George III and Queen Charlotte for over 30 years, referred to the miniature in her journal for 11 January 1764 – 'Cha's picture was finished' – but she did not record the name of the artist.

It has been suggested that the artist may be Nathaniel Hone (1718-1784.) Hone was born in Dublin and came to England where he practised as an itinerant portrait painter. In 1750, he went to Rome and in 1752 became a member of the Accademia del Disegno in Florence. About this time he met Sir Joshua Reynolds and a feud developed between the two men, culminating in a dispute between Hone and the Royal Academy. He exhibited at the Society of Artists from 1760 to 1768 and in 1769 was a founder member of the Royal Academy and exhibited there from 1769 to 1784. In 1775, he submitted his painting The Conjuror to the Royal Academy where it was seen as a caricature of Sir Joshua Reynolds and Angelica Kauffmann, and was refused by the council of the Academy. A contemporary described him as a 'tall, upright, large man, with a broad-brimmed hat and a lapelled coat buttoned up to his stock'.

Inscribed indistinctly on the back in ink: Miss Finch / Legacy from / Ly Cremorne / to Miss ... / 1826, and mounted in a gilt filigree frame.
