I recently met someone with this name, he's from Canada and the way his parents pronounce it is OH-rell. Everyone else said or-ell like orelse... If people aren't mature enough to say it properly that's their problem. I think it's a nice name and if I had a son I'd consider this name.
Who would have thought this is a German name? I like it, though like what the anonymous user above said, it's a character from that show on Adult Swim. I don't really like the show or the AS block. But for those who do like this; if you want to name your kid this, go ahead it won't faze me any. :) It is a nice name.
