Oh yes,
Othniel! I do think it's quite handsome, but it's one of those names I never seem to remember.
Othniel Charles is one awesome combo. It does seem very warm and friendly and like it would fit right in with common names, so it is surprising you don't see it around here or in real life more. I think it would be a fresher alternative to stuff like
Daniel,
Gabriel, and
Ethan.
I think Othie is really cute, and Niel is good, too.
