[name]Hi[/name], [name]Megan[/name], and welcome to namberry! Naming a baby is a big deal, so don’t be hard on yourself for having a hard time choosing. 
You’ll find the perfect name for your baby!
[name]Harlow[/name] isn’t my style, but I do personally associate it with [name]Nicole[/name] [name]Richie[/name]'s baby girl. That said, if you love it and aren’t bothered by the association, then go for it!
[name]Annabel[/name]: The classic [name]Annabel[/name]/[name]Annabelle[/name] is one of my personal favorites, despite it’s gainging popularity. I think it’s elegant and perky at the same time. [name]Annabel[/name] gets my vote!
Anastyn: I have to be completely honest and say that this name is very trendy and, well, not very classy. 
Yooneek spellings don’t make a name unique, but are very downmarket and guarantee your child a lifetime of having to correct people’s spelling. In addition to this, this name, even when spelled correctly, is 100% [name]Jennifer[/name] Aniston to me, and I’m guessing I’m not alone.
Lexiana: An invented name that possesses the qualities I wrote about Anastyn.
What about: [name]Audriana[/name], [name]Juliana[/name], [name]Mariana[/name], [name]Viviana[/name], [name]Liliana[/name]…
[name]Sailor[/name]: It’s not my style, but I think it’s much better than Anastyn and Lexiana…
[name]Kaia[/name]: [name]Kaia[/name] is too trendy for my taste, but I rank it second behind [name]Annabel[/name].
[name]Quinn[/name]: I think [name]Quinn[/name] could be a good choice for you if you’re looking for a unisex name.
Quinnleigh/Quinnley: See Anastyn. The spellings and invented nature of the names don’t make it more feminine, but do make it severely trendy and downmarket.
Perhaps you’d like the surname [name]Quincy[/name]?

I see that popularity/trendiness is an issue for you (the classic [name]Sophia[/name]), so you may want to consider that surnames as first names for girls is very, very trendy. Some surnames feel trendier than others, but the last-names-first thing is indeed a trend.
I wish you the best!
