Everyone wants unique names.

[anamosity.livejournal.com]

I am new and about 6 weeks along. my boyfriend and i have pretty much agreed on a girls name but we are having trouble with a boys. I made more that I liked that I will show him but I'd like some more that are not popular names yet, could be either a very pretty name or a very unique name.
Girls:
arion
autumn rayne (we're leaning towards this)
astrid
echo
aspen
scarlett
riley

guys:
asiris
fenix blaze (this was my original choice but he doesn't like it)
brody
talon
riley
chase
kaos

if you have any to suggest I would appreciate it! Or any middle names that would go nicely with the above names.
Thanks
