Does the Italian suffix "-otta" have any meaning?

Question

I am doing research on my last name, and "-otta" is the suffix. I haven't been able to find info on it, only a bit on "-atti," but that was the closest, and I'm not sure if they are related. Any help would be great!

Answer 1

otta derives from Octavia and is used to denote the eight child born to a family. Going back hundreds of years when people were named after their profession, the area they came from or from physical traits such names were commonplace to enable identification of a particular child. The most common Italian names now are
Feminine Masculine
1 Maria Giuseppe
2 Anna Giovanni
3 Giuseppina Antonio
4 Rosa Mario
5 Angela Luigi
6 Giovanna Francesco
7 Teresa Angelo
8 Lucia Vincenzo
9 Carmela Pietro
10 Caterina Salvatore
11 Francesca Carlo
12 Anna Maria Franco
13 Antonietta Domenico
14 Carla Bruno
15 Elena Paolo
16 Concetta Michele
17 Rita Giorgio
18 Margherita Aldo
19 Franca Sergio
20 Paola Luciano

So if, for example Sergio's eighth child was named Paulo he could be named Paulo Sergiotta.
