Helen Selina Blackwood, Baroness Dufferin and Claneboye (née Sheridan, 18 January 1807 – 13 June 1867), later Countess of Gifford, was a British songwriter, composer, poet, and author. Admired for her wit and literary talents, she was a well-known figure in London society of the mid-19th century. She was the daughter of Thomas Sheridan (a colonial treasurer) and granddaughter of the dramatist Richard Brinsley Sheridan. Edited by her son, Lady Dufferin's songs and lyrics were collected into this volume (1894). Recited by thousands of Irish school children, "The Bay of Dublin," "Katey's Letter," "Terence's Farewell," and "Irish Emigrant's Lament" were the best known.
