The gens Numeria was a minor plebeian family at ancient Rome.
She was mentioned in the ancient prayers recited by the Pontifex Maximus, and Varro writes that the praenomen Numerius was given to children who were born quickly.
[1] As with other gentilicia that share a form with praenomina and cognomina, it is often difficult to determine whether persons named Numerius bore it as a praenomen, nomen, or cognomen.
From extant records and inscriptions, they used primarily Gaius, Marcus, and Publius.
A few Numerii are known to have borne different praenomina, including Quintus, Lucius, and Gnaeus.
