Children of Lir

I love Celtic mythology and was pleasantly surprised by this classic setup of the Children of Lir...
I bought a coffee and went to the estuary to watch the wildlife, intending staying maybe twenty minutes........ Five hours later I headed towards home.....as nobody was waiting for me.....only saying
ps .... very Short version...
"
Bodb Derg was elected king of the Tuatha Dé Danann, much to the annoyance of Lir. To appease Lir, Bodb gave one of his daughters, Aoibh, to him in marriage. Aoibh bore Lir four children: one girl, Fionnuala, and three sons, Aodh and twins, Fiachra and Conn.
Aoibh died, and her children missed her terribly. Wanting to keep Lir happy, Bodb sent another of his daughters, Aoife, to marry Lir.
Jealous of the children's love for each other and for their father, Aoife plotted to get rid of the children. On a journey with the children to Bodb's house, she ordered her servant to kill them, but the servant refused. In anger, she tried to kill them herself, but did not have the courage. Instead, she used her magic to turn the children into swans. When Bodb heard of this, he transformed Aoife into an air demon for eternity.
As swans, the children had to spend 300 years on Lough Derravaragh (a lake near their father's castle), 300 years in the Sea of Moyle, and 300 years on the waters of Irrus Domnann Erris near to Inishglora Island (Inis Gluaire). To end the spell, they would have to be blessed by a monk. While the children were swans, Saint Patrick converted Ireland to Christianity".
