Eloise is adorable, and I love that it is being used. It has such a soft and dainty feel, but still a classical vibe that is charming.
As for
Juliet, I have always liked that name. We considered it briefly, but DH is named
Julius and he has a cousin
Juliet. Still, its a strong yet whimsical name that will always have the romantic feel.
Of yoru combos,
Juliet Mirth really stood out. I love vintage virtue names, and I have only seen that on boys before. It's quite catching on a girl. Unexpected and quirky combo,
Juliet Mirth.
Mailys is one of my favorite names (though I prefer the more modern
Maylis spelling for some uncharacteristic reason!).
Juliet I have never though to pair with it, and I find that it works!
Ivy,
Sylvie and
Frances seems to mesh well with it from your list as well.
For some alternate suggestions, following your word vibe:
Juliet MeadowJuliet Vale
Juliet Esprit
Juliet BlytheJuliet Swift
Juliet Rebel
Juliet NobleJuliet Serene
Juliet Whisper
