I'm kind of reminded of
Lex Luthor, but not so much that it taints the name for me. I'm more reminded of
Martin Luther King, Jr, or
Martin Luther.
I like the name. It's classic and it has a history, while still being unusual nowadays. I like it as both a fn and a mn but prefer it, somewhat, as a fn.
Luther Isaiah is a nice combo.
