Quirinus Quirrell claimed to have received his turban from an African prince in return for ridding him of a zombie. In reality, Quirrell used the turban to hide the face of Lord Voldemort on the back of his head. Therefore, it is possible that this individual does not exist, particularly as there are no wizarding princes, and it would be odd if a Muggle prince knew about a zombie, additionally, zombies are known to be native to South America.
