The gens Sergia (or Sergii), was a famous patrician family in ancient Rome, of which Lucius Sergius Catilina was a member.
Sergii was one of the oldest patrician families in Rome. Although was of consular heritage, Sergii were then declining in both social and financial fortunes.
Virgil later gave the family an ancestor, Sergestus, who had come with Aeneas to Italy, presumably because they were notably ancient; but they had not been prominent for centuries, Sergestusque, domus tenet a quo Sergia nomen.
The last Sergius to be consul had been Gnaeus Sergius Fidenas Coxo in 380 BC.[1]
The Sergii regularly used the cognomina Esquilinus, Fidenas et Catilina.
