The gens Petronia was a plebeian family at ancient Rome. This gens claimed an ancient lineage, as a Petronius Sabinus is mentioned in the time of Lucius Tarquinius Superbus, the last of the Roman kings, but few Petronii are mentioned in the time of the Republic. They are frequently encountered under the Empire, holding numerous consulships, and eventually obtaining the Empire itself during the brief reign of Petronius Maximus in AD 455.
The gens Acilia was a plebeian family at ancient Rome, that flourished from the middle of the third century BC until at least the fifth century AD, a period of seven hundred years. The first of the gens to achieve prominence was Gaius Acilius Glabrio, who was quaestor in 203 and tribune of the plebs in 197 BC.
The gens Aurelia was a plebeian family at ancient Rome, which flourished from the third century BC to the latest period of the Empire. The first of the Aurelian gens to obtain the consulship was Gaius Aurelius Cotta in 252 BC. From then to the end of the Republic, the Aurelii supplied many distinguished statesmen, before entering a period of relative obscurity under the early emperors. In the latter part of the first century, a family of the Aurelii rose to prominence, obtaining patrician status, and eventually the throne itself. A series of emperors belonged to this family, through birth or adoption, including Marcus Aurelius and the members of the Severan dynasty.
The gens Cornelia was one of the greatest patrician houses at ancient Rome. For more than seven hundred years, from the early decades of the Republic to the third century AD, the Cornelii produced more eminent statesmen and generals than any other gens. At least seventy-five consuls under the Republic were members of this family, beginning with Servius Cornelius Maluginensis in 485 BC. Together with the Aemilii, Claudii, Fabii, Manlii, and Valerii, the Cornelii were almost certainly numbered among the gentes maiores, the most important and powerful families of Rome, who for centuries dominated the Republican magistracies. All of the major branches of the Cornelian gens were patrician, but there were also plebeian Cornelii, at least some of whom were descended from freedmen.
The gens Terentia was a plebeian family at ancient Rome. Dionysius mentions a Gaius Terentilius Arsa, tribune of the plebs in 462 BC, but Livy calls him Terentilius, and from inscriptions this would seem to be a separate gens. No other Terentii appear in history until the time of the Second Punic War. Gaius Terentius Varro, one of the Roman commanders at the Battle of Cannae in 216 BC, was the first to hold the consulship. Members of this family are found as late as the third century AD.
The gens Aelia, occasionally written Ailia, was a plebeian family in Rome, which flourished from the fifth century BC until at least the third century AD, a period of nearly eight hundred years. The archaic spelling Ailia is found on coins, but must not be confused with Allia, which is a distinct gens. The first member of the family to obtain the consulship was Publius Aelius Paetus in 337 BC.
The gens Calvisia was an ancient Roman family, which first rose to prominence during the final decades of the Republic, and became influential in imperial times. The first of the gens to obtain the consulship was Gaius Calvisius Sabinus in 39 BC.
The gens Vitellia was a family of ancient Rome, which rose from obscurity in imperial times, and briefly held the Empire itself in AD 69. The first of this gens to obtain the consulship was Aulus Vitellius, uncle of the emperor Vitellius, in AD 32.
The gens Antonia was a Roman family of great antiquity, with both patrician and plebeian branches. The first of the gens to achieve prominence was Titus Antonius Merenda, one of the second group of Decemviri called, in 450 BC, to help draft what became the Law of the Twelve Tables. The most prominent member of the gens was Marcus Antonius.
Caecina was the name of an Etruscan family of Volaterrae, one of the ancient cities of Etruria. Persons of this gens are first mentioned in the first century BC. Under the Empire the name is of frequent occurrence. As late as the reign of Honorius, we read of the poet Decius Albinus Caecina, residing at his villa in the neighborhood of Volaterrae; and until modern times there has been a family of this name at the modern Volterra. The family tomb of the Caecinae has been discovered in the neighborhood of Volterra; in this tomb there was found a beautiful sarcophagus, now in the Museum of Paris.
The gens Cestia was a plebeian family at Rome during the later Republic, and in imperial times. The first member of the gens to obtain the consulship was Gaius Cestius Gallus in AD 35. The family's name is commemorated on two monuments, the Pons Cestius and the Pyramid of Cestius which survive into modern times.
The gens Sosia, occasionally written Sossia, was a plebeian family at ancient Rome. Members of this gens occur in history from the end of the Republic down to the third century AD. The first of the Sosii to attain the consulship was Gaius Sosius in 32 BC, and the family would continue holding various positions in the Roman state until the third century.
The gens Juventia, occasionally written Jubentia, was an ancient plebeian family at Rome. After centuries of obscurity, the gens emerges into history with the appearance of Titus Juventius, a military tribune, in the beginning of the second century BC. The first of the Juventii to obtain the consulship was Marcus Juventius Thalna in 163 BC. But the family is renowned less for its statesmen than for its jurists, who flourished during the second century AD.
The gens Plautia, sometimes written Plotia, was a plebeian family at ancient Rome. Members of this gens first appear in history in the middle of the fourth century BC, when Gaius Plautius Proculus obtained the consulship soon after that magistracy was opened to the plebeian order by the lex Licinia Sextia. Little is heard of the Plautii from the period of the Samnite Wars down to the late second century BC, but from then to imperial times they regularly held the consulship and other offices of importance. In the first century AD, the emperor Claudius, whose first wife was a member of this family, granted patrician status to one branch of the Plautii.
The gens Pupia was a plebeian family at ancient Rome. Members of this gens are mentioned as early as 409 BC, when Publius Pupius was one of the first plebeian quaestors, but over the course of centuries they achieved little of significance, and rarely held any of the higher offices of the Roman state.
The gens Rupilia, occasionally written Rupillia, was a minor plebeian family at ancient Rome. Members of this gens are first mentioned in the latter part of the Republic, and Publius Rupilius obtained the consulship in 132 BC. Few others achieved any prominence, but the name occurs once or twice in the consular fasti under the Empire. The name is frequently confounded with the similar Rutilius.
The gens Satria was a minor plebeian family at ancient Rome. Members of this gens are mentioned in the first century BC, and under the early Empire, but none of them rose higher than the rank of praetor. Otherwise the Satrii are known largely from inscriptions.
The gens Sentia was a plebeian family at ancient Rome. Members of this gens are first mentioned in history toward the end of the Republic. The first of the Sentii to obtain the consulship was Gaius Sentius Saturninus, in 19 BC.
The gens Silia was a plebeian family at ancient Rome. Members of this gens are mentioned as early as the fifth century BC, but first to hold the consulship was Publius Silius Nerva, in the time of Augustus. The Silii remained prominent until the time of the Severan dynasty, in the early third century.
The gens Trebonia, rarely Terebonia, was a plebeian family at ancient Rome. Members of this gens are mentioned in the first century of the Republic, and regularly throughout Roman history, but none of them attained the consulship until the time of Caesar.
