In relation to her writing, the "Westminster Review" gave a very good approximation of her literary skill and emotion laden works. “Of the songs and verses which have been collected in the volume it must be confessed that few of them rise above respectable mediocrity. "The Irish Emigrant" is her best song, and is full of true feeling. "Sweet Kilkenny Town" is intensely Irish, and might fittingly be sung by any of the obscure thousands from Erin who toil for bare existence in the great Republic of the West. In many of her other lyrics we find an echo of Moore, but she lacks his perfection of form and exquisite imagery. It is when she writes in the vernacular that she is in her happiest vein. She sympathised with the peasantry of the land in which she was born, and the great charm of her nature lay, not in the gift of genius—for that she did not possess—but in her sweet and loving Irish heart. That she was endowed with some dramatic power is shown by her comedy, entitled Finesse; or, a Busy Day in Messina. She cannot take rank in literature beside her gifted sister, Mrs. Norton, but her womanhood was richer and more perfect than that of many members of her sex to whom was given "the vision and the faculty divine." It is right that the world should know something of one of the womanliest women that ever breathed, and for this reason Lord Dufferin's biography and the verses which accompany it will be treasured in many homes.” Despite her nineteenth-century popularity, Dufferin's work is now largely obscured, in part by the current critical focus on her sister, Caroline Norton.
