To simplify things I'll use this scale:
*Child
**Teenager
***Adult
****Elderly person
Alba**
Allegra*or**
Elda***
Elisea*
Aurora**
Rubina**or***
Romina***
Mattea**

Zaira*
Valentina**
Elvira***
Faustina**or***
Amedeo**
Crescenzo***
Ferrante***or****
Santi**
Terzo***
Nicola***

Gino**or***
Taddeo***
Let me know if any of these aren't actually used in Italy often, or at all
