Dwynwen is the Welsh Patron saint of Lovers.
In the 5th century, Dwynwen fell in love with a man named Maelon Dafodrill. Maelon returned Dwynwen's feelings but they could not be together, for Dwynwen's father forbade the marriage and her father had already promised her to someone else. Distraught by her love for Maelon, Dwynwen prays she would fall out of love with him.

After falling asleep, or possibly while still awake in a woods she had run to in her distress, Dwynwen was visited by an angel, who appeared carrying a sweet potion designed to erase all memory of Maelon and turn him into a block of ice. God then gave three wishes to Dwynwen; first she wished that Maelon be thawed, second that God meet the hopes and dreams of true lovers and third that she should never marry. All three were fulfilled and, as a mark of her thanks, Dwynwen devoted herself to God's service for the rest of her life
