Portrait of Anna-Maria, Countess of Derwentwater (d. 1723), three-quarter-length, seated, in an ochre dress with an ermine-lined blue mantle, a coronet beside her

The sitter is probably Anna-Maria, Countess of Derwentwater, daughter of Sir John Webb, Bt. of Oldstock, Wiltshire, and, through her mother, granddaughter of John Paulet, 5th Marquess of Winchester. She married, in 1712, James Radcliffe, 3rd Earl of Derwentwater (1689-1716). Her husband, a great-nephew of King James II, was one of the most tragic and romantic figures in the Jacobite rebellion of 1715. He was executed on Tower Hill at the age of twenty-eight, and was finally buried at Thorndon, in the family vault of his son-in-law, Lord Petre. The Countess is the subject of the lament, Farewell to Lochaber, said to have been written by her husband on the eve of his departure for the Rebellion. Kneller painted a group portrait of the Earl and Countess with a child, and an engraving by Vertue survives of a portrait of the Earl by Kneller, c. 1714, three-quarter-length, in coronation robes.
