Older authors who follow Plutarch deem her to be the daughter of Quintus Servilius Caepio and Livia, thus the younger full sister of Servilia Major and Gnaeus Servilius Caepio[1] and half-sister to Cato the Younger and Porcia.
Some modern historians such as Susan Treggiari tend to believe that she was actually the daughter of Gnaeus Servilius Caepio, thus a niece of Cato; but this is not universally accepted, Judith P. Hallett has argued that is implausible that the younger Caepio (who was born in 98 BC) would have married so young and sired a daughter fast enough that she would be old enough to marry Lucullus in 66 BC.
[3] Lucullus married her on his return from the Third Mithridatic War around 66 BC, after divorcing his first wife Claudia.
[5] Lucullus, after putting up with her conduct for some time out of regard to Cato the Younger at length divorced her.
On the outbreak of the civil war in 49 BC, she accompanied Cato, with her child, to Sicily, and thence to the Roman province Asia.
