 Julia's daughters by her second husband Marcus Vipsanius Agrippa were Julia the Younger and Agrippina the Elder, not Vipsania Tertia and Vipsania Quarta.Likewise, Agrippina the Elder's daughters were Agrippina the Younger, Drusilla, and Livilla, and not named for their father's adoptive family, the "gens" Julia.Likewise, in the family of Octavia the Younger and Mark Antony, the naming patterns for their daughters (Antonia Major and Antonia Minor) and Octavia's by her first husband (Claudia Marcella Major and Claudia Marcella Minor) are conventional, but that for their granddaughter Livilla (daughter of Nero Claudius Drusus) is not.
