The first full-length biography of one of the most celebrated Irish-language folk poets of the 19th century contains new English-language translations of Mary O'Learys entire poetic canon, including her best-known song, "The Battle of Keimaneigh" (Cath Chim an Fhia), a stirring description of an armed clash in 1822 between militia troops and a secret society of Catholic tenant farmers known as the Whiteboys.
