[Facts] Re: Typical question, sorry!!!!
I don't think anyone here will think this was a typical question, Rohan -- you do have an unusual name. In fact, I'll bet Daividh (with his Celtic heritage) would be the first to tackle this one if he was on-line right now.
I've found two possible meanings:
1. "Rohan" is an English variation of the Sanskrit name "Rohana", which means "the sandalwood tree". If you're into incense-burning, then you might want to make sandlewood incense your personal choice on account of your name. :)
2. "Rohan" is an Irish surname used as a first name, and is probably derived from the Irish word "ruadhan" meaning "red". "Rohan" may also be a variant of the name "Rowan" -- after the rowan tree (a.k.a. the mountain ash) which is commonly found in Scotland. I'll bet Daividh's seen a lot of those rowans in his wanderings thru the olde country. :)
