The gens Postumulena was an obscure plebeian family at ancient Rome. Few members of this gens are mentioned in history, but others are known from inscriptions.[1]
The nomen Postumulenus belongs to a class of names formed primarily from other gentilicia, using the suffix -enus.[2] In this case, the nomen is a lengthened form of Postumius, derived from the old Latin praenomen Postumus. This name is derived from the adjective postremus, "hindmost" or "last", and originally referred to a last-born child, although in later times it was confused with posthumus, "after burial", being applied to children born after their fathers' death.[3]
The only praenomina associated with the Postumuleni are Lucius, Marcus, and Gaius, the three most common names throughout Roman history, and perhaps Publius, known from a filiation, and also very common.
