Edwards dates the Wrest Park Portrait to 1545–1549, the early years of her widowhood after the death of her husband, and gives this description:Together the NPG and Ottawa portraits depict the second and third acts of a life-drama involving the execution of Lady Dacre's first husband and her severely reduced circumstances as a young widow, her long and determined struggle to regain lost wealth, lands, titles and status, and the ultimate success of her quest.
Recently, the Wrest Park Portrait, long said to be of Lady Jane Grey, has been identified as Mary Neville Fiennes, Lady Dacre, by Dr. John Stephan Edwards.
