You're thinking along the lines of generational suffixes? There were Roman emperors who's family name (nomen gentilicium) was a number, the same number being used by son, father, grandfather... not incrementing with each generation.
There were also Roman emperors who's fathers had been slaves.
Lucius Septimius Severus - family name means 7th
Publius Helvius Pertinax - family name means honey-yellow. Son of a freed slave.
