I much perfer
Conrad over
Konrad, and I love the name. Meanings are also very important to me, and I would use it in a heartbeat...if it wasn't popular. (I try to stay away from anything in the top 1000.)
I don't like
Cord though, or double mn. But
Conrad Lucas Trey H. doesn't sound half bad. I don't like combos with the same number of syllables, but
Trey helps un-balance it, as I would say.
It certainly doesn't clash with
Killian, and therefore it works for me.
