Not finding out gender but can't find any names we like enough

[BubbleAndSquark]

We've got a couple of names one or the other of us like but not any we like enough to decide on, from the type of names does anyone have any suggestions to add?

Casper
Jasper
Ashton
Cody

Sophie
Layla

Love Casper and Jasper. Not keen on Sophie or Layla. You have two quite posh boys names and two 'American' boys names, so it's hard to get a sense of what you like.

Aspen
Jason
Caspian
Archer
Cole

Sonya/Sonia
Sasha
Lyra
Lexi
Lilah

I had Casper and Jasper on my boys list (DH vetoed both) but here's the rest of my list.
Jack
Harry
George
Joshua
Leo
Ethan
Lucas
Sebastian
Zachary
Jasper
Tobias
Hayden
Tristan
Casper
Quinn
Barney
Hugo
Hugh

For girls you have a classic in Sophie, so I'd suggest Charlotte, Annabel or Lucy might be on par. Then you have Layla which I would consider more of a pretty name/European , so perhaps would suggest Lydia, Gabriella, Aurelia, Emilia?
