Nonia (gens)

The gens Nonia was a plebeian family at ancient Rome. Its members first appear in history toward the end of the Republic. The first of the Nonii to obtain the consulship was Lucius Nonius Asprenas in 36 BC. From then until the end of the fourth century, they regularly held the highest offices of the Roman state.

The nomen Nonius is a patronymic surname, based on the praenomen Nonus, presumably belonging to an ancestor of the gens. The name is undoubtedly Latin, although the first of the Nonii to rise to prominence at Rome is said to have come from Picenum. Another branch of the family seems to have come from Aesernia.

The chief praenomina of the Nonii were Lucius, Marcus, and Publius, all of which were used by the Nonii Asprenates, while the Quinctiliani used Lucius and Sextus, the latter coming from the Quinctilii, in the maternal line. The Nonii Galli used Marcus and Gaius, while the Macrini used Marcus and Publius. Other praenomina occasionally appear among Nonii whose connection to the main branches of the family, if any, is unknown, including Aulus, Gnaeus, and Quintus Titus is given in some sources as the earliest ancestor of the Asprenates, solely from the filiation of the consul of 36 BC, but this is very uncertain, and the name is not otherwise found among the Nonii.
