They're the only two common soldiers mentioned by name in De Bello Gallico, I believe -- the characters in Rome were named after them for that reason :)

Rome is interesting. Classically it's fairly accurate, but it also likes to take the old stories and twist them a bit. For example, the rumour that Octavian slept with Caesar as a young man? In Rome, the rumour starts because Caesar's having an epileptic fit and Octavian squirrels him away in a convenient closet until he recovers. A servant sees them go into the closet, hears the grunting of Caesar having his fit, and tells Octavian's mother, who praises him for "getting in good" with his uncle. :D
