Help with first/middle names that honor grandparents!

We're having twins...a boy & a girl. We come from close knit families & we really wanted to honor our parents for everything they've done for us.

The names are Matthew, Matilda, Amelia & Salvatore.

Here are some variations we came up with....if you have any other suggestions, feel free to add!

Matilda/Matthew:

Boy: Matteo, Mattieu, Matias

Girl: Mattea, Mattia, Tilly

Amelia:

Boy: Emilio, Milo

Girl: Mila, Amalia, Mia, Leah

Salvatore:

Boy: 🤷‍♀️ maybe Salvatore with the nn Torre or Salvo?

Girl: Salvatrice, Salvatrix, Tory, Sally, Sarah (I read that Sally is a diminutive of Sarah).
