We are expecting twin boys. We have one son already, named Keegan. Now, we already decided on girl names, obviously those are no good. We've stopped discussing boys' names at this point because we just aren't feeling it. We picked Kellen and Karsen BUT, we have some setbacks; 1: Do we really want our twins to have similar names (or all 3 of them, for that matter)?

2: Is it too cheesy to stick with "K" names?

We think all of those names are great boy names (separately) and the all have solid middle names, Edward, David and Thomas. Opinions, ideas or thoughts, Ladies?
