The Cloak of Invisibility was passed down Ignotus' family line and eventually ended up in the hands of his final known descendants, the Potters. It eventually ended up in the hands of James Potter I, the father of Harry Potter. James used the Cloak of Invisibility in many of his mischiefs at Hogwarts School of Witchcraft and Wizardry and kept it afterward. Around the time that Lord Voldemort was hunting the Potters for their son, the Cloak of Invisibility came to the attention of Albus Dumbledore when James showed him the Cloak of Invisibility, and Dumbledore who had searched his entire life for the Deathly Hallows and already possessed the Elder Wand, another of the Deathly Hallows asked to borrow the Cloak from James to study its properties. After James was killed, the Cloak was left in Dumbledore's possession.
