So it happened that the lad, who went out of his mother's cottage, in the morning, a poor boy, came back to her, a rich man, and leading by the hand the loveliest creature on whom man or woman had ever looked upon.
As for the old man and the other daughter, no one ever saw them again.
Gwyn and his wife went out to a farm which he bought, and oh, how happy they were! She was very kind to the poor. She had the gift of healing, knew all the herbs, which were good for medicine, and cured sick folk of their diseases.
Three times the cradle was filled, and each time with a baby boy. Eight long and happy years followed. They loved each other so dearly and were so happy together, that Gwyn's vow passed entirely out of his mind, and he thought no more of it.
On the seventh birthday of the oldest boy, there was a wedding at some distance away, and the father and mother walked through a field where their horses were grazing. As it was too far for Lady Nelferch to walk all the way, her husband went back to the house, for saddle and bridle, while she should catch the horse.
"Please do, and bring me my gloves from off the table," she called, as he turned towards the house.
But when he returned to the field, he saw that she had not stirred. So, before handing his wife her gloves and pointing playfully to the horses, he gave her a little flick with the gloves.
Instead of moving, instantly, she heaved a deep sigh. Then looking up at him with sorrowful and reproachful eyes, she said:
"Remember our vow, Gwyn. This is the first causeless blow. May there never be another."
Days and years passed away so happily, that the husband and father never again had to recall the promise given to his wife and her father.
