Middle name

Na
I just found out we're having a girl, and need suggestions to consider for a middle name after "Lydia". 
My grandmother recently passed; her name was Grace, so we are considering Lydia Grace, but I also want other options.
 My great-grandmother was Saveria, which is the feminine of Xavier in Italian, and we also like that for a middle name because it's different.. 
What do you guys think? I'm open to all suggestions, I just need some help to get our brains going! Looking through books can be so draining, everything sounds terrible after a while lol.
