A name like Jem :D (Please read info inside!)?

It's to replace a character's name in the book I'm writing. When I started I had two characters named Jem ,and both are important, and now I have to change ones name. One is a fairy, the other a gypsy that helps the main character. I want the name to be kind of like Jem, either it has three letters, or a letter(or letters) the same(like Jem and Mel), or have a close meaning. Thanks! :D
