Sextia gens

The gens Sextia was a plebeian family at ancient Rome, from the time of the early Republic and continuing into imperial times. The most famous member of the gens was Lucius Sextius Lateranus, who as tribune of the plebs from 376 to 367 BC, prevented the election of the annual magistrates, until the passage of the lex Licinia Sextia, otherwise known as the "Licinian Rogations," in the latter year. This law, brought forward by Sextius and his colleague, Gaius Licinius Calvus, opened the consulship to the plebeians, and in the following year Sextius was elected the first plebeian consul. Despite the antiquity of the family, only one other member obtained the consulship during the time of the Republic. Their name occurs more often in the consular fasti under the Empire.

Origin
The nomen Sextius is a patronymic surname, derived from the praenomen Sextus, meaning "sixth", which must have belonged to the ancestor of the gens. It is frequently confounded with that of the patrician gens Sestia, and in fact the two families may originally have been the same; however, Roman authors treated them as distinct gentes. The plebeian gens Sextilia was derived from the same praenomen.

Praenomina
The main praenomina of the early Sextii were Marcus, Lucius, and Gaius, the most common names throughout all periods of Roman history. From filiations, we know that some of them also used Numerius and Sextus, of which the former was relatively uncommon at Rome. Later generations of this gens used Publius, Titus, and Quintus, all of which were also common. Epigraphy provides instances of Vibius, a name that was also used by the patrician Sestii, supporting the theory of a common origin.

Branches and cognomina
Most of the Sextii under the Republic bore no surname, or else had only personal cognomina, instead of family-names. These included Baculus, Calvinus, Lateranus, Naso, Paconianus, and Sabinus.
