Hello! so older brothers are Santino and Raffaele (parents Italian)
Angelina would be nice to match Santino as it means “little angel” and Santino means “little Saint”. Isabella because mom’s name is Lisa which derives from Elizabeth and Isabella is Italian for Elizabeth.
Last name is Clemente!
Both options seem great for you!
I personally prefer [name_f]Isabella[/name_f] and I also like it for you because it honors you mom. But [name_f]Angelina[/name_f] is a good idea as well, the meaning is very cute.
Both are lovely but [name_f]Angelina[/name_f] is so full of flair and matches with your boys
[name_f]Angelina[/name_f] [name_m]Clemente[/name_m] for this one
[name_f]Angelina[/name_f] [name_m]Clemente[/name_m] goes perfectly with her brothers names !
[name_f]Angelina[/name_f] is a very pretty name that goes well with the other names and maybe her middle name could be [name_f]Elizabeth[/name_f]? [name_f]Angelina[/name_f] [name_f]Elizabeth[/name_f] [name_m]Clemente[/name_m]. 
I love both, but I definitely prefer [name_f]Angelina[/name_f]
I prefer [name_f]Angelina[/name_f] with her brothers! [name_f]Isabella[/name_f] is a nice honor, but I don’t think it is quite the stylistic match that [name_f]Angelina[/name_f] is.
I love [name_f]Angelina[/name_f]!
I like Angelina! It’s more unique and very beautiful!
Lisa - Elizabeth - Isabella is way too lose a connection for me… Isabella is a pretty name. But I know a lot of Isabella’s and zero Angelina’s!
