Claudia Marcella
Tacitus described her as the grand-niece of Augustus. For a long time it was uncertain how exactly she was related to Augustus, with many assuming she was a daughter of Claudia Marcella Major but historian Ronald Syme reports that an inscription from Asia confirms she was the daughter of that consul of 29 BC Sextus Appuleius and a sister of Publius Quinctilius Varus. She had a brother also named Sextus Appuleius.
