Thank you everyone for all of your suggestions!! I want to comment on them, because I still don’t feel like I have found the “right combination” yet, and maybe this can help finding it. I really appreciate the feedback thus far:
[name]Kate[/name] [name]Michelle[/name] - [name]Michelle[/name] sounds a little dated to me
[name]Kate[/name] [name]Lauren[/name] - ditto with [name]Lauren[/name]
[name]Kate[/name] [name]Gabrielle[/name] -
[name]Kate[/name] [name]Nicole[/name] - dated
[name]Kate[/name] [name]Alexis[/name] - dated - not a fan of [name]Alexa[/name], [name]Alexis[/name], [name]Alexia[/name], etc.
[name]Kate[/name] [name]Alexandra[/name] - like
[name]Kate[/name] [name]Evangeline[/name] -
[name]Kate[/name] [name]Eleanora[/name]
[name]Kate[/name] [name]Genevieve[/name] -
[name]Kate[/name] [name]Josephine[/name]
[name]Kate[/name] [name]Louisa[/name] - kind of like… Maybe [name]Kate[/name] [name]Eloise[/name] or [name]Kate[/name] [name]Louise[/name]?
[name]Kate[/name] [name]Mirabel[/name]/[name]Mirabelle[/name] - no
[name]Kate[/name] [name]Marielle[/name] - I like the [name]Mary[/name] beginning of it… on the right track but, don’t think [name]Marielle[/name] is “the one”
[name]Kate[/name] [name]Miranda[/name] - love the name [name]Miranda[/name]
[name]Kate[/name] [name]Rosalie[/name] - like Rose___ but [name]Rosalie[/name] reminds me of Twilight and I am not a big fan. 
[name]Kate[/name] Rosabel/[name]Rosabelle[/name] - maybe
[name]Kate[/name] [name]Sophia[/name] (popular name, though) - I like the softness of this… but yes, [name]Sophia[/name] is really popular. but this could work
[name]Kate[/name] [name]Victoria[/name] - not a fan of [name]Victoria[/name]
[name]Kate[/name] [name]Elisabetta[/name] - I think I would probably use [name]Elizabeth[/name] over [name]Elisabetta[/name]
[name]Kate[/name] [name]Avery[/name] - I kind of like. I usually don’t like using unisex names, but this combo looks nice and sounds nice.
[name]Kate[/name] [name]Paloma[/name] - no, think of soap
[name]Kate[/name] [name]Briar[/name] - too harsh
[name]Kate[/name] [name]Saoirse[/name] - no idea how to pronounce
[name]Kate[/name] [name]Melisande[/name] - ditto
