My rough edit.... verdicts please

Everly- ok sounds very American (nothing wrong with that!)
Edie- quite like
Aiya- only if spelt Aya
Aerin-no
Phoebe- LOVE
Lila/Lilah- like
Maggie- no
Amber-ok
Tallulah-ok
Leni-no
Quinn-no
Scarlet-ok
Willa-ok
Erin-ok

Boys
Brody- ok
Kitt- like
Leo-like
Buster-no
Zac-like
Nate-ok
Tate-ok
Jude- LOVE
Rex-LOVE
Rafftery- Like

I like Willa, Phoebe, Kitt (but much prefer with one t), Leo and Nate (if it's short for Nathan/Nathaniel).

Edie is OK but feels a bit nicknamey to me, plus it's a big celebrity/trendy choice at the moment so I think it will date quickly. Aerin is nice in theory but I think she'd constantly be referred to as Erin. Most of the rest are a bit too 'American' for me.

Girls
Everly - don't like at all
Edie - always loved this
Aiya - don't like
Aerin - unusual but lovely
Phoebe - like
Lila/Lilah - not keen
Maggie - I actually like this
Amber - it's alright
Tallulah - just no.
Leni - not keen
Quinn - prefer this for a boy

Boys

Aiya - don't like it

Tallulah - okay
Leni - no
Quinn - it's alright - I prefer it for a boy!
Scarlet - I like it, but prefer the double t!
Willa - I don't like, but Willow is nice!
Erin - nice

Boy:
Brody - I like it, but prefer the 'Brodie' spelling.
Kitt - no... Kit is better, but still a no
Leo - really like!
Buster - dog
Zac - I prefer Zachary, but 'Zack' for a name (Zac is a nickname for Isaac, IMO)
Nate - prefer Nathan/Nathaniel...
Tate - nope
Jude - I don't like it, it's not bad, though...

Seekingmiracles i think it also depends on your last name - My surname requires spelling every single time, so giving her an awkward first name and surname may be a bit mean, but if your last name is relativley simple i dont think it would be as much of a problem.

I can't get on board with Buster. It just creates a mental image of a "gut buster" greasy spoon fry up. It's just a not very nice sounding word.

And then there's Buster Bloodvessel

I like Lila, Willa and Leo

I like Willa, Erin and Leni (also like this as a nickname for Helena) from your girls list.

From the boys list I like Nate and Leo

I love Edie!!! (This is one of my absolute favourite ever names, but i'm always concerned she will be mistaken for Eddie and will constantly have to tell people her name)

Next favourites are Erin and Scarlet for girls and Nate (short for Nathan or Nathaniel) and Zac

I'm not keen on Pheobe, Willa (but i quite like Wilhelmina, shortened to Mina) or Leni (how about Leonie instead?)

I don't like Brody (the only Brody's i know are girls and they are horrible people, put me off the name for life)

Love Erin and brody
Only one I'm not keen on is buster

Girls- I love Leni and Scarlett
Boys - Brody and Jude
