The gens Acerronia or Aceronia was a minor plebeian family at Rome during the late Republic and early Empire.
The consul Gnaeus Acerronius Proculus was originally from Lucania, although Cicero mentions someone of this name living at Rome at least a century earlier.
[4][5] 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.
[7] 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.
[11] 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.
