Acerronia gens

The gens Acerronia or Aceronia was a minor plebeian family at Rome during the late Republic and early Empire. The most distinguished member of the gens was Gnaeus Acerronius Proculus, consul in AD 37. A number of Acerronii are known from inscriptions.

Origin
The nomen Acerronius belongs to a large class of surnames, largely of plebeian origin, typically formed from cognomina ending in -o. Chase does not list the name among the gentilicia of this class, or mention it among the gentes for which origins could be readily determined. Those Accerronii not found at Rome are chiefly located in southern Italy. The consul Gnaeus Acerronius Proculus was originally from Lucania, although Cicero mentions someone of this name living at Rome at least a century earlier. An excavated sanctuary building from Regium Julium in Bruttium, and dating from the first century BC, includes a fragment of an architrave with a dedicatory inscription to Mefitis. Archaeologists believe that the family was behind the building activity and identified Proculus or his grandfather as the person mentioned in the inscription.

Praenomina
The Acerronii used a variety of common praenomina, including Aulus, Gaius, Gaeus, and Marcus, as well as the less-common Numerius, a name typical of families from central and southern Italy. An inscription from Narbo in Gallia Narbonensis might mention a Lucius Acerronius, but the reading of the nomen gentilicium is uncertain.

Branches and cognomina
Two cognomina are associated with the Acerronii mentioned in history: Proculus, originally a praenomen, was a common surname in imperial times. Polla, the feminine form of Paullus, was probably a personal name, although by imperial times women's individualizing names were usually treated as cognomina, despite functioning as the praenomina from which they were frequently derived. Posilla, found in an inscription is also a personal cognomen of this type, and like Polla or Paulla bore the meaning of "little", typically a name for a younger daughter. Celer, meaning "swift", was a common surname throughout Roman history. Puteolanus, found in a sepulchral inscription, indicated that the bearer was originally from Puteoli in Campania, while Eleutheria, belonging to an Acerronia buried at Tarentum, as a Greek theophoric name was likely the name of a freedwoman.
