[3] In 1884 the portrait was used as an illustration in a collected edition of her letters published by Lord Brabourne, a relative of Jane Austen.
[6] In 2019 the owners revealed a letter allegedly written by Jane Austen's great-niece Fanny Caroline Lefroy describing the history of the portrait.
[8] In 2012, research and forensic work was undertaken using digital analysis of photograph negatives from 1910 held in the Heinz Archive & Library taken prior to a later poor cleaning and over-painting of the portrait.
This digital enhancement is said to show that the signature of Ozias Humphry, and the name Jane Austen is visible on the photograph.
