This may sound totally wierd, but after I was half-way through my novel, I started writing the elvish language for it. After I got the language fairly developed, I went in and looked for the meanings of my character's made up names.

To my complete and total surprise, I had unintentionally created name meanings in the language that not only fit the sylables for my characters (root, prefix, and suffix-wise), but that also fit thier personalities. I was pretty excited and totally amazed: believe me it was totally coincidental.
My suggestion to you might be to look up the meaning of the name you want to use (like "Jordan"), and then translate the meaning into your language, which might then make it seem more authentic.
