↑ Titus ialah praenomen; Livius itu nomen bermaksud "berbangsa Livia". Therefore, Titus Livius did not have the cognomen, the third name, the family name, which was not unusual during the Roman Republic. About this the classical sources agree: Seneca (Ep. 100.9), Tacitus (Ann. IV.34.4), Pliny (Ep. II.3.8) and Suetonius (Claud. 41.1) call him Titus Livius; Quintilian calls him Titus Livius (Inst. Or. VIII.1.3; VIII.2.18; X.1.101) or simply Livius (Inst. Or. I.5.56; X.1.39). In the sepulchral inscription from Patavium, which most probably concerns him, he is named, with the patronymic, T Livius C f "Titus Livius Cai filius" (Templat:CIL).
