Another of her dramas, of which she had neglected to keep a copy, was "Who's Who?" which was in the possession of Tyrone Power when he was lost in the SS "President" in April 1841. In 1840, she issued what has been called the best of her novels, "Marian, or a Young Maid's Fortunes", in which her knowledge of Irish character is again displayed in a style equal to anything written by Maria Edgeworth. Her next work was a series of "Stories of the Irish Peasantry", contributed to "Chambers's Edinburgh Journal," and afterwards published in a collected form. In 1840 she aided her husband in a book chiefly composed by him, "Ireland, its Scenery, Characters, &c." She edited the "St. James's Magazine" in 1862–63.
