Very specific boys name help

I’m looking for a boys name that means something along the lines of teacher or knowledge that starts with R.
I’m having a harder time than I expected but I love this site so I thought, if anyone would know…!

Honestly, I’m not actually having a baby, I’m writing a story, but i love reading this site just for fun so i thought this would be the best place to start!
I’m going to keep looking but any help would be great!


never mind I think i’ve found some things!
