Gaius Octavius
Marcus Appuleius is postulated to have been the son of Sextus Appuleius and Octavia the Elder, therefore making him related to the emperor Augustus through his grandfather Gaius Octavius. For many years associated with the quaestor of Asia in 45 BC who joined Marcus Junius Brutus after the assassination of Julius Caesar, this is now held to have been his uncle of the same name.
