Hello,
There are several D'Andrea family trees on Ancestry and most have the same information about Louis and Liberata. Your tree is possibly one of them.
Here is what I would do. Email the commune Premia,
premia @ ruparpiemonte.it (no spaces)
and ask them for the marriage record for Louis and Liberata.
Here is a good site to get your letter.

One of the trees I saw suggested Liberata's surname is Cerata. Another tree said that Louis father was Charles and mother was Spranza Gaspari.
If you can get the marriage record, you should get the names of the parents.
I think you know the family lived in Arizona in 1900.
Good luck to you,
Paul
