What are the Sicilian Form of various Italian Surnames

[Edward Keeports]

Carrozza
Loiacono
Renda
Cusimano
Polizzi
Oliveri
Campo
Narisi

[James Snavely]

I know Polizzi is Pulizzi in Sicilian (https://en.wikipedia.org/wiki/Polizzi_Generosa)
I think Campo would become Campu (Many towns that begin Campo- become Campu- in Sicilian)
Don't know about the others

[James Snavely]

Lo Iacono is Lu Jacunu in Sicilian

Thank you James Snavely

I recognize all of those names, except Narisi, as being common in Sicily, particularly the western part (Palermo, Agrigento, Trapani). They were spelled the way you've written them or with the following variations:

Lo Iacono (with a space) or just Iacono. I've never seen it written any other way.
Renda or Renna. This is a Sicilianism, changing "nd" to "nn." (For example, the number 11 is "unnici" in Sicilian.)
Cusumano. (In Agrigento I always see it spelled this way; I believe it's the same name.)
Polizzi or Pulizzi.
Oliveri. I've never seen another variant.
Campo or Di Campo.
