Griselda is a famous folklore figure, noted for her patience and obedience. Her story has been told by Petrarch, Chaucer, Boccaccio and set to music by Scarlatti, Vivaldi and Massenet.
In the most famous telling of her story, Griselda's husband tests her fidelity and obedience three times. Once at the birth of her daughter, whom he asks Griselda to give up to be put to death. Griselda agrees. Her husband asks the same of their second child, a son. Again, Griselda agrees. Finally, her husband renounces her to marry another. Uncomplainingly, Griselda leaves. Eventually her husband reveals that he was testing her, and surprises her by showing her her alive and well children and taking her back in.
Griselda is Anglicized as Grisell or Grizell. Zelda makes an attractive nickname option.
