I don't know how often the site is/was updated, but another ranch that bought most of his horses a few years back told me he filed bankruptcy...so it's likely it hasn't been updated since he did so. He's also not computer savvy, so I'm assuming someone else updated the website before that (Probably CNR Quarter Horses).. but she could've been sold as a weanling, or sold right when he filed bankruptcy and never made it to the site, because I got her in 2010... She wasn't halter broke when I got her. So my theory is that she was either A. Sold in a hurry, sooner than her could get to training her, B. Supposed to be a broodmare, but it didn't pan out or C. Anything other number of other circumstances lol.
Well, it is up to date until late 2011 at least, there are 2011 weanlings for sale. He should be able to identify her and since he offers these pedigrees weanlings, more than likely yours has papers too. If he's the breeder, he can help you with AQHA then.
