I was wondering if any of the ancient Roman patrician and plebeian families still had descendants carrying their surnames today. I went to Cognomix, and searched for what the modern surnames would sound like without the -us ending. It turns out that not only most of the famous ancient surnames are still present, but the vast majority are still found in central Italy today - not just in Lazio, but also quite a lot in Tuscany, Umbria, Marche and Abruzzo.
Here are the Patrician families I could find. The others are probably extinct or their names became heavily corrupted.
- Aquili (gens Aquilia) : 126 families today, including 71 in Marche, 23 in Lazio and 13 in Umbria.
- Attili (gens Atilia) : 259 families today, including 113 in Lazio, 53 in Marche, 34 in Umbria and 26 in Abruzzo.
- Claudi (gens Claudia) : 100 families today, including 26 in Lazio, 18 in Marche and 16 in Toscana.
- Comini (gens Cominia) : 684 families today, including 425 in Lombardia (maybe another origin or the family moved there early in Roman times), 26 in Lazio, 19 in Marche and 18 in Toscana.
- Corneli (gens Cornelia) : 203 families today, including 40 in Umbria, 24 in Lazio, 27 in Marche and 24 in Toscana.
- Curti (gens Curtia) : 2395 families today, including 956 in Lombardia (same as the Comini), 309 in Emilia-Romagna, 302 in Piemonte and 263 in Lazio.
- Ermini (gens Herminia) : 791 families today, including 535 in Toscana and 97 in Lazio.

What we observe is that these patrician names are found overwhelmingly in central Italy, especially in Lazio, but represent only a small part of the population today.
And now for a few renowned Plebeian families.

- Ulpiani (gens Ulpia) : 28 families today, including 24 in Lazio.
The pattern is similar, but with a stronger presence in northern Italy for some families.
