She produced two more notable works. The first was "" (1962), a history of the Great Irish Famine of the 1840s that was critical of the British government's handling of the famine, in particular singling out Sir Charles Edward Trevelyan for criticism, although she did acknowledge that the British government assisted during the first phase of the famine. The second was the first volume of "Queen Victoria: Her Life and Times" (1972). She was unable to complete the next volume of the biography, and died in London in 1977 at the age of 80.
