Would you all use these as a sibset: [name_f]Milena[/name_f] Ósk, [name_f]Katerina[/name_f] [name_f]Ivalo[/name_f] and [name_f]Adrienne[/name_f] Svala?
Brother would be [name_m]Benjamin[/name_m] [name_m]Oslo[/name_m]…other boy names to come 
Thanks!!
Yes, I think those are gorgeous choices!
[name_f]Milena[/name_f] and [name_f]Katerina[/name_f] seem more Slavic to me than [name_f]Adrienne[/name_f], which seems more Romantic/Latin/Italian. I think [name_f]Milena[/name_f], [name_f]Katerina[/name_f] and [name_f]Aviana[/name_f] seem more like natural sisters than [name_f]Adrienne[/name_f].
I agree that [name_f]Adrienne[/name_f] doesn’t quite fit with [name_f]Milena[/name_f] and [name_f]Katerina[/name_f]. I do love [name_f]Adrienne[/name_f] but I think from you signature, [name_f]Eliska[/name_f] and [name_f]Dominika[/name_f] fit better.
I think they go nicely together.
I think they sound lovely together. Although I do agree with others that [name_f]Adrienne[/name_f] doesn’t fit quite as well, as it’s Greek not Slavic.
I like [name_f]Adrienne[/name_f] is fine, but a possible alternative that might fit a little better is [name_f]Adrianna[/name_f].
