NAME A CHARACTER

How would you like to name a character in one of my upcoming books? Or, at least, half of a name? You see, I need a last name for a character and I figured I could ask you guys for help. In the comments, shout out some ideas for last names and I'll pick my favorite. And to make it extra special, whoever has the winning last name will get their name mentioned in the acknowledgment section of said book. Also, I'll send you a free copy when the book publishes. But that could be a while from now so don't forget! 

Here's a little insight on the character, or as much as I can give right now. He's a man named Jeffrey and he's from the Southern United States. He comes from a sketchy past and kills for a living. That's as much as I can give you. Have fun and good luck.
