I think most of them could work well!
Juliet Elizabeth - very classic, I prefer a bit more life but no one can hate [name]Juliet[/name] [name]Elizabeth[/name], it’s a fine name.
Jacqueline Eden - not sure about the matching N endings, I also find [name]Jacqueline[/name] slightly stuffy, [name]Eden[/name] is lovely though!
Katherine Noelle - this is more interesting, [name]Noelle[/name] is quite unusual where I’m from so I think it complements the popular [name]Katherine[/name] very well.
Charlotte Marie - [name]Love[/name] them both separately but, again, a little plain together.
Eliza Catherine - FAVOURITE!
Eve Augusta - I rally like this and also the pp of [name]Eve[/name] [name]August[/name], two vowel-names okay together though?
Isla Rose - I think [name]Isla[/name] needs a stronger mn, [name]Rose[/name] seems like a filler in this spot
Maeve Elizabeth - [name]LOVE[/name] IT! [name]Maeve[/name] is top of my list too
