Trueman

Don't get me wrong, I like the sound of this name. It's very handsome. But I would use the variant Truman instead; it looks like less of a compound word. It would also be ironic on someone who isn't "true", but honestly, many people aren't. So it's not a big deal. You should certainly be your best self, and never let others force you to be someone you're not.

Good name for a true man.

I wouldn't name my kid this, it's saying "true man" like, what if your kid lies? Hm?
