"The Wexford Carol", sometimes known by its first verse "Good people all this Christmas time", is of uncertain origins, and, while it is occasionally claimed to be from the early Middle Ages, it likely was composed in the 15th or 16th century based on its musical and lyrical style. The song achieved a renewed popularity due to the work of William Grattan Flood (1859–1928), who was organist and musical director at St. Aidan's Cathedral in Enniscorthy. He transcribed the carol from a local singer and had it published in The Oxford Book of Carols, putting Enniscorthy into most carol books around the world. https://en.wikipedia.org/
