Dzhugashvili or Jughashvili is a Georgian surname, a transliteration of ჯუღაშვილი.
The former priest who is considered by some to be the novel's villain, Cimourdain, purportedly "made a deep impression on a young Georgian seminarian named Dzhugashvili, who was confined to his cell for reading Ninety-Three and later changed his name to Stalin", according to a biographer of Hugo.
