|Fenrir Greyback's wand|
Garrick Ollivander (possibly)
Greyback did attend Hogwarts School of Witchcraft and Wizardry(source needed), so it is probable that he purchased this wand at the age of eleven like most witches and wizards. It may have been purchased at Ollivander's Wand Shop.
In 1998, Bellatrix Lestrange overpowered Greyback and his Snatchers and took his wand during a dispute at Malfoy Manor after Harry Potter and his friends were captured. She returned his wand to him shortly before she began her interrogation and torture of Hermione Granger.
