[name_f]My[/name_f] first daughter is [name_f]Sophia[/name_f] [name_f]Eve[/name_f]. I love [name_f]Charlotte[/name_f] [name_u]Sage[/name_u], DH is liking [name_f]Maia[/name_f] [name_u]Skye[/name_u], but doesn’t feel any name has really made him fall in love. (he is waaaaay more difficult than I am lol) I am very picky because of how names sound with our last name (Melchiorre). Suggestions please! 
[name_f]Sophia[/name_f] [name_f]Eve[/name_f] is lovely. [name_f]Charlotte[/name_f] [name_u]Sage[/name_u] is nice, but both [name_f]Sophia[/name_f] and [name_f]Charlotte[/name_f] start with an s sound…
[name_f]Maia[/name_f] [name_u]Skye[/name_u] doesn’t really have a great flow, and an M first name might sound a bit funny with your last name. I really like [name_u]Sage[/name_u] or [name_u]Skye[/name_u] as a the middle name!
Suggestions:
[name_f]Chloe[/name_f]
[name_f]Nicolette[/name_f] or [name_f]Colette[/name_f]
[name_f]Juliet[/name_f] or [name_f]Julia[/name_f]
[name_f]Amelia[/name_f]
[name_f]Nina[/name_f]
Ok in my opinion charlotte should be called [name_f]Charlotte[/name_f]. [name_u]Charlie[/name_u] is a boys name (if you were thinking of doing this ). Especially if her sister is sophia. Secondly, [name_u]Sage[/name_u] I never know if that name is a boy or a girl. I think charlotte skye is the best option out of your list, then you both can use a name you like. [name_f]Sophia[/name_f] eve is so feminine and classic, sweet and simple(and biblical). What about [name_f]Charlotte[/name_f] [name_f]Anne[/name_f] or [name_f]Charlotte[/name_f] [name_f]Maeve[/name_f]. [name_f]Charlotte[/name_f] [name_f]Joy[/name_f]. [name_f]Charlotte[/name_f] [name_f]Hope[/name_f]

I love both [name_f]Charlotte[/name_f] and [name_f]Maia[/name_f] as those are my daughters names. I don’t think there is any problem with a double M with your last name - either choice sounds great. I personally like different middle names but of [name_u]Sage[/name_u] and [name_u]Skye[/name_u] I like [name_u]Sage[/name_u] best.
