The Three Daughters of King O'Hara: An Irish Animal Bridegroom Tale
A King had three daughters. One day while he was away, the eldest put on a cloak of darkness and wished for the most beautiful man under the sun as a husband, and a beautiful man came and took her away.
The middle daughter saw this, and put on the cloak and wished for the best man in the world as her husband. The youngest put on the cloak and wished for a white dog, and they were each taken away.
When the king came home he was furious his youngest daughter had wished for a white dog and gone off with him.
The eldest daughter's husband asked her if she would like him to stay in his current form at night, or during the day. She asked for his human form in the daytime, and he was a seal at night. The same thing happened to the next sister.
The youngest wife asked for her husband to remain a white dog during the day, and at night he became a handsome man. After a time she bore a son, and her husband warned her, if anything happened to the child, she must not shed a tear. While her husband was gone, a great crow came and carried the week old baby away, and she did not shed a tear.
The same thing happened after she bore a second son. A little while later, she gave birth to a daughter. Despite the warning, when the crow carried her away, the wife shed one tear, and put it in her handkerchief. When her husband came home and realized she had shed a tear, he was very angry.
Some time later, the father invited his three daughters to stay with him. The white dog was in dread that he would not be allowed to stay in the palace, but his wife told him, "There is no danger to you, for wherever I am, you'll be, and wherever you go, I'll follow and take care of you."
Although the King did not want the dog in his castle, his youngest daughter did not listen to him, and insisted on staying with the white dog all evening. Later, when everyone was in their rooms, the Queen and the cook stole into her daughter's rooms, and was surprised to see her eldest daughters with seals, and her youngest with a handsome man. The Queen also found the white dog skin, and threw it in the fire.
The skin gave a crack that woke everyone in the castle, and everyone for miles around. The youngest daughter's husband was angry, and revealed that if he had spent three nights with his wife under her father's roof, he could have resumed his human form permanently; but if his skin was destroyed, he was forced to leave. But his wife followed him, even though he ran all night and the next day; she would not leave him.
On their journey, they encountered three houses. In the first lived a little boy who called her "mother", and the woman of the house gave her a pair of scissors that would cut rags and turn them into new gold clothes. In the second house the woman met another little boy who called her "mother," and was given a magical comb that would heal sores on people's heads and give them a head full of beautiful golden hair. In the third, she met a little girl with one eye. The mother had kept the handkerchief in which she had shed a tear, and the tear had turned into an eyeball; the mother took out the eye and fitted it into her daughter's head, and she could see out of it. At this home she was given a whistle which would bring birds to her aid.
Finally, the husband and wife came to a place where he had no power to stay on upper earth, but was forced to become the husband of the Queen of Tir na n-Og (the land of youth), and he disappeared. His wife followed down until she came to the lower land, where she befriended a poor washer woman, and helped her with her chores.
One of the local children came to the wife in rags, and she used the magic scissors to make her beautiful new clothes. News of this traveled to the Queen, who insisted on having the scissors for herself. The true wife traded the scissors for a night with the Queen's husband, where she tried to talk to him, but he slept all night.
Later, she used the comb to heal a little girl with sores all over her head, and when the Queen heard of the girl's beautiful golden hair, she traded the comb for a night with her husband, but the same thing happened.
The wife used the whistle to call the birds to her, and they told her how to kill the Queen: her husband must find her heart in an egg in a duck in a wether (a neutered male sheep-thanks, Sue Bursztynski!) in a holly tree in front of the castle, and destroy the egg, which contained her heart. The true wife wrote her husband a letter, telling him of their history and that the Queen was giving him sleeping potions, and how to kill the Queen. Once the Queen heard about the whistle, the true wife was able to strike the same bargain, but this time her husband was awake; he was able to obtain the egg and smash it, killing the evil Queen. He and his first wife are still living happily together in the Land of Youth.
