Situation..

I love, love, love the name Nash, Dash or Bash. I don’t want to just name him one of them though.. I don’t feel I’d get good opinions on it.. so I’m looking for longer names that these could be used as nicknames. I know Dash can be short for Dashiell but I’m not a fan.. and Bash can be short for Sebastian but I’m not sold. Any suggestions?? Or opinions on me just naming him one of these without a longer name?
