Biography provided by the Metropolitan Museum of Art)
 
Henrietta Augusta was the next youngest sister of Lady Caroline Nevill; daughters of William Nevill, 4th Earl of Abergavenny, both were given every encouragement and resource to develop their accomplishments. Caroline and Augusta (as she was known) turned to photography, perhaps stimulated by a family friend, William Thoms, editor of the lively journal Notes and Queries, who took a great interest in the new art. Much of their work was portraiture of their aristocratic family done with collodion negatives. In the 1854 exhibition of the Photographic Society in London, the sisters exhibited jointly under the name “The Ladies Nevill.” They must have been stung by the review in the Athenaeum, which sniped that their portraits “report to us the improved employment of their leisure by some members of the aristocracy of the present day.” Having exhibited under the name Lady Henrietta Nevill before her marriage in 1855 and afterward as Lady Augusta Mostyn, Lady Augusta contributed to the albums of the Photographic Exchange Club in 1855 and 1856. For these pictures of architecture in Sussex and in Kent, she used waxed-paper negatives.
