 Apart from the praenomen, the "filiation" was the oldest element of the Roman name.Even before the development of the nomen as a hereditary surname, it was customary to use the name of a person's father as a means of distinguishing him or her from others with the same personal name, like a patronymic; thus Lucius, the son of Marcus would be "Lucius, Marci filius"; Paulla, the daughter of Quintus, would be "Paulla, Quinti filia".Many nomina were derived in the same way, and most praenomina have at least one corresponding nomen, such as Lucilius, Marcius, Publilius, Quinctius, or Servilius.
