Congratulations!!
Seeing how excited you are about your first baby has made me smile I wish you all the best with your new addition 
[name_f]Luna[/name_f] feels very international honestly the ultimate universal choice. [name_f]Luna[/name_f] is beautiful celestial choice. Some other names with that fashionable lilting L start which feel international are [name_f]Lilia[/name_f], [name_f]Liliana[/name_f], [name_f]Liliosa[/name_f], [name_f]Leila[/name_f], [name_f]Lyra[/name_f], [name_f]Lila[/name_f], [name_f]Lola[/name_f], [name_f]Lena[/name_f], [name_f]Leonora[/name_f], [name_f]Leona[/name_f] and [name_f]Leonie[/name_f].
I also love [name_f]Esther[/name_f]! She’s a lovely biblical choice really strong, classic and timeless. I also love the meaning ‘star’ she’s just gorgeous. Some other choices could be [name_f]Ruth[/name_f], [name_f]Naomi[/name_f], [name_f]Noemi[/name_f], [name_f]Lydia[/name_f], [name_f]Hannah[/name_f], and [name_f]Abigail[/name_f].
[name_u]Evelyn[/name_u] is very classic she’s elegant, sweet and timeless. Names that could also work are [name_f]Evelina[/name_f], [name_f]Adeline[/name_f], [name_f]Charlotte[/name_f] and [name_f]Elizabeth[/name_f].
[name_f]Sylvia[/name_f] is lovely! I really like [name_f]Sylvie[/name_f] but also [name_u]Silver[/name_u] is a great idea to honour a [name_f]Sylvia[/name_f]. In relation to boys [name_m]Sylvan[/name_m] could work. I think [name_m]Sylvan[/name_m] could be a good idea. I also love [name_m]Silas[/name_m] have you thought of [name_u]Forest[/name_u]? [name_f]Sylvia[/name_f] means ‘from the forest’ so could [name_u]Forest[/name_u] be an idea! I love the idea of [name_u]Forest[/name_u].
[name_u]Benjamin[/name_u] is such a lovely name! A really strong biblical name that feels handsome, wholesome and has sweet nicknames. I love [name_u]Benjamin[/name_u]. I think [name_u]Benjamin[/name_u] [name_u]Silver[/name_u] would be gorgeous. You may also like [name_m]Samuel[/name_m], [name_m]Reuben[/name_m], [name_u]Gabriel[/name_u], [name_m]Nathaniel[/name_m], [name_m]Abraham[/name_m] and [name_u]Noah[/name_u].
[name_m]Lucas[/name_m] is a nice name he has a relaxed laid back friendly vibe. However I do prefer [name_u]Luca[/name_u]. I think [name_u]Luca[/name_u] is gorgeous. Some other ideas could be [name_u]Elias[/name_u], [name_u]August[/name_u] and Otis/Otto.
[name_f]Hope[/name_f] this helps
