Thomas Crofton Croker (1798-1854), was an Irish antiquary, born at Cork. For some years, he held a position in the Admiralty, where his distant relative, John Wilson Croker, was his superior. Croker devoted himself largely to the collection of ancient Irish poetry and Irish folklore. He assisted in founding the Percy Society and the Camden Society. He and his wifeâ¿¿s testimonies about funereal customs, particularly the tradition of keening the deceased are among the earliest and most significant contributions to the understanding of the Irish language lament and the accompanying traditions. His work South of Ireland went to six editions, it was translated into German by the Brothers Grimm. His works include: Researches in the South of Ireland (1824), Fairy Legends and Traditions of the South of Ireland (1825-27), Popular Songs of Ireland (1837), Daniel Oâ¿¿Rourke (1829) and Barney Mahoney (1832).
