Mary Lepelle was a famous court beauty who married John Hervey in secret in 25 October 1720. She was the daughter of Brigadier General Nicholas LePelle. Fairfax Murray identified a second drawing of Lady Mary Hervey by Richardson in the Morgan Library, New York, in the Bull album. John Wilson Croker, who edited the first edition of Mary Lepelle's Letters in which the present drawing is included, was a friend of John Mitford (1781-1859) to whom this book first belonged. Mitford formed an important book collection which was auctioned by Sotheby’s after his death in 1859 and realised the sum of £2,999.
