Nonia gens

[1] The nomen Nonius is a patronymic surname, based on the praenomen Nonus, presumably belonging to an ancestor of the gens.

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.

[10] Beginning in the mid-second century there is a family with the surname Macrinus, a diminutive of the cognomen Macro, a Greek name meaning "great" or "large".

This family distinguished itself through military and civil service, and evidently obtained patrician rank, as Marcus Nonius Arrius Paulinus Aper was advanced to the office of praetor without having first served as tribune of the plebs.
