Kind of funny, I feel the opposite about them--I think
Jeb seems more down-to-earth than
Jed.
Jep? It's kind of cool, and I'm always instantly drawn to any medieval nickname. I'm not so sure how much I like the sound, though. But I do really love
Jem! If we ever had another boy
James is the likeliest name right now, and I'd definitely call him
Jem sometimes.
Judicael is a good one! I just noticed that name a few days ago for the first time. Pretty awesome.
