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.
