Call Me a Dreamer

While looking for fairy lore about handkerchiefs in response to this post by asakiyume, I came across the following story on the SurLaLune Fairy Tales website: The Three Daughters of King O'Hara. This story is from the book Myths and Folklore of Ireland by Jeremiah Curtin. I'd never come across this story before and was really delighted with it as it combines elements of a number of different fairytale motifs.
