The gens Gallia was a plebeian family at ancient Rome. Several members of this gens are mentioned during the first century BC. [1]
The nomen Gallius might be derived from Gallus, a common surname that can refer either to a cock or someone of Gallic origin.
Among the Gallii we find the praenomina Quintus, Marcus , and Gaius , all of which were common throughout Roman history. [1]
The Gallii do not appear to have been divided into distinct families, and none of those known during the late Republic bore any surnames.
