Roman Emperor (Principate) Antony's daughter who was also Augustus' niece, Germanicus Julius Caesar. Germanicus married Vipsania Agrippina, Agrippa's daughter by Julia and Tiberius's stepdaughter, and had by her one surviving son, Gaius "Caligula" ("Little Boots"), and a daughter, Julia Agrippina, whose third husband was Germanicus's brother by blood, Claudius (she was his fourth wife); Agrippina had already borne a son, Lucius, whom Claudius adopted under the name Nero"' in 40; Nero married Claudius's daughter Claudia Octavia in 53. The year 69 is often called the "Year of the Four Emperors" because it saw four usurpers successively claim the purple robe. The fourth Emperor,
Vipsania Marcella Vipsania Marcella Vipsania Marcella Agrippina or Marcellina or Vipsania Tertia (born 27 BC or later) was perhaps the only daughter of Roman statesman Marcus Vipsanius Agrippa by his second wife Claudia Marcella Major. If so, she was the first grandchild to Octavia Minor and first great-niece to Roman Emperor Augustus. If she truly had the name Marcella, there is no way that she was a daughter of Agrippa's first wife, Caecilia Attica. She and her elder sister Vipsania Agrippina were married off to Quintus Haterius (cos. 5 BC), Publius Quinctilius Varus (cos. 13 BC) and Tiberius (also cos. 13 BC)
