I gave my daughter this name, only we spelled it Karlyn. I used to really regret that decision, but it has grown on me. It's hard to imagine her with a different name.The people who like the name like the fact that it's different without being "out there". Plus, there's always the option to use the nickname Karly.The most annoying part of having a kid with this name is that people always mispronounce it and call her Karolyn.
