Need some good ideas for J names.

My hubby and I would like to stick with the J name tradition. My name is Jasmine and his is Jordan. Trying to choose something that isn't already taken on his side of the family. Which are James, Jean, Jessica, Jamie, Jake, John, and Joanne. We wanted to do something a little unique, but not to crazy. Lol. Still don't know the gender. But I was thinking Jayden for a boy or Jaylin for a girl. Thoughts?
