I would want to go with another A name also. But I like cohesion.
Boys
I like [name_u]August[/name_u]
I’ll suggest
[name_m]Atticus[/name_m]
[name_m]Anthony[/name_m]
Girls
[name_f]Alice[/name_f]
[name_f]Amelia[/name_f]
[name_f]Anya[/name_f]
[name_f]Alicia[/name_f]
[name_f]Annais[/name_f]
[name_f]Anna[/name_f]
[name_f]Annabeth[/name_f]
[name_f]Annabell[/name_f]
[name_f]Amelie[/name_f]
[name_u]Andrea[/name_u]
[name_f]Agatha[/name_f]
[name_f]Agnes[/name_f]
[name_u]Antonia[/name_u]
[name_f]Astoria[/name_f]
[name_f]Alexia[/name_f]
[name_f]Amara[/name_f]
[name_f]Abigail[/name_f]
I think my favourite for this family would be [name_f]Amelie[/name_f]. It has that femininity of [name_f]Aurora[/name_f] and a classic vibe like [name_m]Alexander[/name_m].
