Клавдия Марцелла
She was a daughter of Claudia Marcella Minor and the Roman consul of 12 BC, Marcus Valerius Messalla Appianus. Her maternal grandmother was Octavia the Younger, sister of Augustus. There has been some speculation among historians such as George Patrick Goold that her father might actually have been Publius Claudius Pulcher (the son of Clodius) but others such as Ronald Syme have rejected this proposal.
