Cool names for characters?

I love names that are short and simple, but I also like names that are long and old-fashioned but still cool. I usually use the short ones as nicknames. But I need some more names.

Names I have:

Jeremy "Jei" (his initials, sort of)

Kallen "Kale"

Tobias "Toby"

Alex (for a girl)

Thello

Aire

Frederick "Eric"

I like names that are made up or unique, but cool. My favorites are ones like "Aire" "Jei" and one I didn't mention "Eli"

Do you have any names like those that I can use? I especially like names that start with vowels. :)

btw: these are names for characters in a manga/comic i'm making with my cousins. it takes place in America so different language names are fine too.
