Biography
Mac Coisdealbhaigh was in love with Úna Ní Dhiarmaida but her family refused to allow them to marry. After several attempts, Mac Coisdealbhaigh made a last formal proposal, swearing that if he crossed Áth na Donóige on his way home without receiving an answer, he would never marry Úna. "He rode slowly and waited a long time in the ford itself, but finally on the mocking advice of his own servant, he crossed to the opposite bank. A messenger came soon after with news that he had been accepted, but he refused to go back on his oath. Úna died shortly afterward. Tomás killed the servant who gave him the evil counsel, and composed the famous song Úna Bhán."
