Needing help with boy's name

Emily
My husband has this crazy tradition in his family where when the first born son has his first son the name has to start with a J. Not too fond of this tradition but I'll go with it. I already have 2 sons from my first marriage. Their names mean brave and knightly. I would like to have a strong, unique and masculine kind of name for my little bean if that's what we are having. I was thinking Jameson but not sure. Ideas would be awesome.
