Daughter of Lir...
Noleen is a version of the Irish name Fionnuala, which means “bright shoulder” in context of being an attribute of the moon. In Irish mythology, Fionnuala was a daughter of Lir.
After Bodb Derg became king, in order to keep Lir happy, he sent him one of his daughters, Aoibh to marry. The two had four children – Fionnuala and three boys, Aodh and twins Fiachra and Conn.
When Aoibh died, Bodb wanted to keep Lir happy so he sent him another one of his daughters, Aoife, to marry Lir. She quickly became jealous of the children and the love they had for their father.
On a visit to see Bodb, Aoife used her magic to transform the children into swans. Upon hearing of this, Bodb turned Aoife into an air demon for eternity.
Fionnuala and her brothers would spend 900 years as swans. Three hundred would be spent at Lough Derravaragh, 300 hundred years at Sea of Moyle, and finally 300 years at Irrus Domnann. They would remain this way until the marriage of Lairgreen, son of Colman, and Deoch, daughter of Finghin, would break the curse.
