Would this be for the birth father.
Faye's parents living in Italy?
First names that came in mind were Italian names Valentino or Del Piero but than again you've not mentioned if they originated from Italy or Americans migrated to Italy.
So thinking of other last names I came up with: Houston, Baker, Mitchell, Davis .......
It could be anything but I don't know if it suits your character. Because it also depends on what he's like, his behaviour. Is he friendly or rude. Acting like a real snob or is he someone with a good hart you know a good samaritan.
Any way I wish good luck on your book.
ps I think a good name for your book would be: Hope
Just "Hope" because finding out she's being adopted after such a horrific act which cost her the life of her adoptive parents her hope would be to have her real parents. Parents that hopefully love her as much as her adoptive parents did.
From the moment Faye finds out about her real parents every steps she takes and makes, literally everything is driven by... ...HOPE...
* Let me know when you finished your book. I would like to read it because I think it will be a beautiful journey. And I like to know how it ends.
Personally I like the name Jesse
As for more last names suggestions: Morrison,Walker, Preston, Donovan, Emerson, Brennan, Serrano, Marquez, Doyle, Keller, Haynes, Miller, Garcia, Morales, Cameron, Redding….
I’m still a bit clueless on what will fit your character. lol
Other name suggestions:
It could be anything.
Hope you can make a decision.
Again, best of luck!
