Having said that, here is what I understand about Cherokee names. It is not authorative nor exhaustive, but as I live nowhere near anyone who speaks Cherokee, I am pretty isolated from it all. Being an outcast doesn't help either.
Cherokee names are Cherokee. while it is possible to translate them into English, or for that matter, any other earthly language, they don't tend to translate into single words, like Bob, or Bill.
English names, like names from around the word also have meaning. For istance, my own name, David, is hebrew for beloved (though I doubt many people would apply THAT label to me. to make my name into a Cherokee name could take a couple of different courses.
If you're at this site, you've probably seen the movie 'Dances with wolves'. In that movie, The protaganist was named as the result of something he as seen doing. This is a common theme in native american culture. I'm not sure how well it translates into Cherokee, but there it is.
