Drusus Julius Caesar
In 11 BC he married Vipsania Agrippina, daughter of Marcus Vipsanius Agrippa and his first wife Caecilia Attica, and the former wife of Tiberius. Their union proved fruitful and produced at least six children. Gallus also claimed true paternity of Drusus Julius Caesar, earning him Tiberius' animosity. If Gallus' claim was true, he might also have been the father of the child Vipsania was expecting on her divorce.
