one of the most celebrated of the Roman gentes, was in all probability originally patrician, as we can hardly conceive that the first consul, L. Junius Brutus, connected as he was with the family of the Tarquins, could have been a plebeian, although the latter hypothesis is maintained by Niebuhr. But however this may be, it is certain that, with the exception of the first consul and his sons, all the other members of the gens were plebeians. [BRUTUS.] The family names and surnames which occur in the time of the republic are, BRUTUS, BUBULCUS, GRACCHANUS, NORBANUS, PACIAECUS, PENNUS, PERA, PULLUS, SILANUS: the few who are mentioned without any cognomen are given below, under JUNIUS. Many Junii appear under the empire with other surnames than those mentioned above, but of course they cannot be regarded as any part of the real Junia gens: of these an alphabetical list is likewise given below.
