Personally, I find [name]Nicole[/name] and [name]Natalie[/name] a little dated, and [name]Carly[/name] and [name]Paige[/name] are quite trendy at the moment - as names like this date the fastest, I try and avoid them. (That said, [name]Charlotte[/name] [name]Jean[/name] would be a lovely name, and [name]Carly[/name] could be a nn option.)
[name]Chloe[/name] is also quite popular, which is something I try and avoid - there’s nothing wrong with the name at all, I just think when some of your other choices are rarer, it’d make sense to opt for them instead.
[name]Audrina[/name], although not my favourite name (I do like [name]Audrey[/name] though, so no exactly sure where my problem with it lies), does sound good with [name]Jean[/name] - I’m pronouncing them to rhyme, so it gives the vintage combination a bit of spunk.
I adore alliteration, but because [name]Julie[/name] is only two syllables, the J and EE sounds repeat too close together in [name]Julie[/name] [name]Jean[/name], and it makes it a little hard to say. To get to the nn [name]Julie[/name], [name]Juliet/name and [name]Jubilee[/name] both sound fantastic with [name]Jean[/name]. Other J names you might like in first place are [name]Junia[/name], [name]Juniper[/name], [name]Jessamine[/name], and [name]Jacinta[/name].
[name]Elizabeth[/name] is popular, but obviously a classic, and comes with so many nicknames to add a bit of pizazz - thumbs up.
[name]Miriam[/name] is a beautiful name, feminine but not fussy, familiar but not too popular, and the combination has fantastic flow. Nns [name]Mira[/name] and [name]Miri[/name] are lovely, too.
[name]Molly[/name] is a lovely, down-to-earth vintage choice, not too out-there but not yet too popular in the US (I’m in the UK, where it ranks higher up). She sounds very sweet with [name]Jean[/name], but the name would work just as well on an adult. You might also like names like [name]Polly[/name] and [name]Elsa[/name].
Good luck!
