Vipsania

Reportedly, Tiberius once ran into Vipsania again, and proceeded to follow her home crying and begging forgiveness; soon afterwards, Tiberius met with Augustus, and steps were taken to ensure that Tiberius and Vipsania would never meet again.

After Agrippa died in 12 BC, Tiberius was ordered to divorce his own wife Vipsania and marry Agrippa's widow, Augustus' daughter Julia — as soon as a period of mourning for Agrippa had ended.

Eck (2003), 116. Drusus' marriage to Antonia was considered an unbreakable affair, whereas Vipsania was "only" the daughter of the late Agrippa from his first marriage.

Indeed, Tacitus calls it Tiberius' intima causa, his innermost reason for departing for Rhodes, and seems to ascribe the entire move to a hatred of Julia and a longing for Vipsania.

Less well known is Agrippa’s oldest daughter - Vipsania Marcella.
