I'm not very familiar with Italian names...
Maria is the one that sticks out to me because it's the only one I see a lot.
Luigi makes me think of
Mario Bros.
The three
Gi- names stick out to me as a group (I esp. like
Giada and
Giovanni together), which makes
Luigi and
Maria seem mismatched in comparison.
I'm also wondering why only Guiseppe and
Maria got a second name.
