It's not...

I took some writing samples, and it's not:

1. Daren
2. Gary
3. Debbie
4. Jim
5. Julie
6. Vonne
7. Kim
8. Todd
9. Robert
10. Claudia
11. Reed
12. Brent
13. Kelly
14. John

It might be Ron. It's very likely that it is Charlie. But there's a unique twist which also points to Daryl Lynn. And just what does Johnny Cash have in common with Chicago, Fort Worth and Martinsburg West Virginia?
