Sibling for Mila

I have a daughter named [name_f]Mila[/name_f] and I am looking for sibling idea for a second on the way.
I tend to like shorter names, and international names (easy for my European family to pronounce) and there will be no second name (just my maiden name as their middle name).

A few that are already in mind but not 100% on:

[name_f]Adele[/name_f]
[name_f]Elsa[/name_f]
[name_f]Vera[/name_f]
[name_f]Neve[/name_f] (n-ehv)
[name_f]Eline[/name_f]
[name_f]Lenor[/name_f]
[name_f]Solene[/name_f] (sol-ehn)
[name_u]Loren[/name_u]
[name_f]Elena[/name_f]

[name_m]Roman[/name_m]
[name_m]Xavier[/name_m]
[name_m]Miguel[/name_m]
[name_u]Noel[/name_u]
[name_m]Gabriel[/name_m]
[name_m]Rafael[/name_m]

I am open to new suggestions, or thoughts on the existing.

Thank you for your help!

When you say European, what part of Europe do you mean? Is it [name_m]French[/name_m], Italian, [name_m]German[/name_m], Slavic…?
from your list I like:
[name_f]Vera[/name_f]
[name_f]Elena[/name_f]
[name_m]Roman[/name_m]
[name_m]Xavier[/name_m]

For girls, [name_f]Mila[/name_f] and [name_f]Elena[/name_f] sound great together, and for boys [name_f]Mila[/name_f] and [name_m]Roman[/name_m].
I feel like the pronunciation of [name_f]Neve[/name_f] and [name_f]Solene[/name_f] wouldn’t transfer well into the English speaking world. If I saw them written down I’d say Neev and Soleen.

Thanks for your suggestions, enwmn!
