I quite like
Echo, but for a girl. Although, I do think it'd be interesting on a boy.
Prarie and
Paisley I'm unsure of...although I do see
Paisley as girl for some reason. Prairie I'm indifferent on for now...but it does remind me of Little House On The Prairie, which makes me think of the Ingalls girls, so I'm thinking girl.
Wednesday I love for a girl! It's a gp of mine and I'd love to actually use it! It used to be a nickname of mine when my dark hair was longer and I'd wear it in braids. It actually sounds nice to be called Wednesday :)
