Cadmus Peverell's fiancée

"Meanwhile, the second brother journeyed to his own home, where he lived alone. Here he took out the stone that had the power to recall the dead, and turned it thrice in his hand. To his amazement and delight, the figure of the girl he had once hoped to marry, before her untimely death, appeared at once before him. Yet she was sad and cold, separated from him as by a veil. Though she had returned to the mortal world, she did not truly belong there and suffered. Finally the second brother, driven mad with hopeless longing, killed himself so as to truly join her."

- The Tale of the Three Brothers

According to legend, the woman Cadmus Peverell loved died prematurely of unknown causes. Although Cadmus attempted to use the Resurrection Stone he had taken from Death to bring her back to the world of the living, she was unable to fully return to life, existing as "neither ghost nor truly flesh". In his despair, Cadmus committed suicide in order to be with her again.

Behind the scenes

 * The Gaunt family are direct descendants of Cadmus Peverell, so it is certain that Cadmus had at least one child in his lifetime. It is not specified if this woman was Cadmus Peverell's wife, or if Cadmus had fathered children from a previous or later relationship. However, as Albus Dumbledore believed that, in reality, the Deathly Hallows had not been gifts from Death but rather inventions of the Peverells themselves, it is also possible that the circumstances of Cadmus' death were embellished somewhat with the passing down of the legend.
