The gens Trebelliena was an obscure plebeian family at ancient Rome. The only member of this gens who achieved any importance in the Roman state was Titus Trebellienus Rufus, who attained the rank of praetor, and was appointed governor of Thrace by Tiberius in AD 19. [1]
The nomen Trebellienus belongs to a class of gentilicia formed using the suffix -enus, typically used to form nomina from existing gentilicia ending in an i stem. [2] Here the name is formed from the nomen Trebellius .
