Helvia (gens)
The gens Helvia was a plebeian family at Rome. This gens is first mentioned at the time of the Second Punic War, but the only member of the family to hold any curule magistracy under the Republic was Gaius Helvius, praetor in BC 198. Soon afterward, the family slipped into obscurity, from which it was redeemed by the emperor Pertinax, nearly four centuries later.
