Alice Amelie, or Jack Arthur

Looking for names to go with our son [name_m]Ethan[/name_m] [name_m]Hugo[/name_m]. Most of the names we like are fairly classic, [name_m]Oscar[/name_m], [name_m]Leo[/name_m], [name_m]Jack[/name_m], etc. But we are finding [name_m]Ethan[/name_m] is quite ‘American’ and struggling to find something that ties together. (We’re [name_m]New[/name_m] Zealanders). We are pretty sold on [name_f]Alice[/name_f] for a girl. [name_f]Do[/name_f] you think they go together? And quite like [name_m]Jack[/name_m], but worry its a bit too common/boring. (I grew up with an unusual name so less interested in needing one for my kid.) Any suggestions? Particularly boys!
