So far most of our family/friends say [name_f]Olivia[/name_f] flows best, [name_f]Isabel[/name_f] is OK, and [name_u]Wren[/name_u]/[name_f]Anabelle[/name_f] don’t flow. I really like [name_u]Wren[/name_u], but I can see how it would be better to choose a multi-syllable name.
Thanks for the suggestions! I think [name_f]Aurelia[/name_f], [name_f]Alexandra[/name_f], or [name_f]Emilia[/name_f] might work. I probably should have mentioned that it will be said often by Spanish speakers as well as Redneck speakers, making it hard to find something that sounds nice both ways.
What about [name_f]Arwen[/name_f] or [name_u]Arden[/name_u]? Before I even saw your suggestions, the letter W came to my mind!
[name_f]Wilhelmina[/name_f], [name_f]Winona[/name_f], [name_f]Willa[/name_f] or [name_f]Willow[/name_f] all seem like great middle names!
