In Goidelic mythology, King Conchobar of Ulster planned on marrying his step-daughter, the beautiful Deirdre. She fell in love with his nephew, Noise; they fled to Scotland with his two brothers (sons of Usnech). Conchobar's messengers asked Noise and his brothers to return to Ireland. They did and he killed them; one of his courtesans, Fergus mac Roich, left his court in protest. Deirdre died of grief.
