Ooo that’s tough. Both are great options so you really can’t go wrong. I give the slight edge to [name_f]Lorelei[/name_f] [name_f]Nova[/name_f] because it avoids repeating the long i sound. [name_f]Lola[/name_f] is a great and creative nickname for [name_f]Lorelei[/name_f].
[name_f]Lorelei[/name_f] [name_u]Piper[/name_u]…I think the repeating vowel sounds actually adds to it! But [name_f]Lorelei[/name_f] [name_f]Nova[/name_f] is beautiful too:)
