Looking for a Gaelic last name for my GW2 characters.

Hey everyone.  I'm looking for a Gaelic last name for my GW2 characters!  I was looking for something with the meaning like Battlecrier or Hornblower.  Or some kind of martial music type name.  I'm planning my Warrior around Warhorn and Shouts so I think it'd be cool to have something like this.  If nothing else I'll go with Iosaig which is the Gaelic form of my real life last name, but I dunno.

The only thing I've found so far is "sluagh-ghairm" meaning army call or gathering call.  Is there a way to make this apply to a person?  Or something like this?  Anyone have any suggestions?

This is a great name generator. You can pick different sources for names and than click on them to get more info. Some of the catdgories include by culture like Irish than some things like Ancient Celtic. It has been a huge resource for me for characters for all games and Rpg's I have played. Hope it helps. http://www.behindthename.com/random/
