[name_f]Do[/name_f] [name_m]Oliver[/name_m] [name_m]Thomas[/name_m] “[name_u]Ollie[/name_u]” and [name_f]Luna[/name_f] [name_f]Charlotte[/name_f] “[name_f]Lulu[/name_f]” make a good sibset? I’m an HP fan so is using [name_f]Luna[/name_f] too weird?

They’re perfect together! Not at all weird to use [name_f]Luna[/name_f]. [name_f]Luna[/name_f] Lovegood is a great character! And the name fits in with other two syllable girl names ending in ‘a’, like [name_f]Emma[/name_f], [name_f]Lila[/name_f] and [name_f]Freya[/name_f].
I too think they fit wonderfully.
both very melodical and meaningful (at least to me). love the middles as well!
I think they’re adorable together. I love the nn [name_f]Lulu[/name_f] and [name_u]Ollie[/name_u] as well.
