[name_f]Fleur[/name_f] [name_f]Cecile[/name_f] [name_m]Fox[/name_m] and [name_f]Lyra[/name_f] [name_u]Evelyn[/name_u] [name_m]Blanchard[/name_m] are my picks! 
[name_f]Opal[/name_f] [name_f]Cecile[/name_f] [name_m]Blanchard[/name_m] and [name_f]Claudia[/name_f] [name_u]Evelyn[/name_u] [name_m]Fox[/name_m], or [name_f]Leda[/name_f] [name_u]Evelyn[/name_u] [name_m]Blanchard[/name_m] and [name_f]Ottilie[/name_f] [name_f]Cecile[/name_f] [name_m]Fox[/name_m] would also be cute!
I really, really want to vote for [name_f]Lyra[/name_f] and [name_f]Ottilie[/name_f] together, but obviously that’s a no-go. You have a lot of really brilliant options!
