In Irish mythology, Finnguala was the daughter of Lir of the Tuatha Dé Danann. In the legend of the Children of Lir, she was changed into a swan and cursed by her stepmother, Aoife, to wander the lakes and rivers of Ireland, with her brothers Fiachra, Conn and Aodh, for 900 years until saved by the marriage of Lairgren, son of Colman, son of Cobthach, and Deoch, daughter of Finghin, whose union broke the curse. 'The Song of Fionnuala', with lyrics by Thomas Moore speaks of her wanderings.
