There are 193 countries in the world. If we excluded every name that appears in popular culture in any country in the world, we would all end up with names like Aaelailel. If the name is Gandalf, Megatron, Drizzt, or any other name that at least a minority of the geek world knows about, dont bother, choose another name. Adding to it might make it acceptable, like Organdal, Mergat, or Dritez might work for you, but do NOT try Gandhalff, Meghatrronn, or Driizzzt because it will get stomped. Hope that helps.
