How would I find a horse?

I do not know the breed but I do know with AQHA you can call them and ask them. One say I received a phone call from someone who almost bought my gelding before me. They asked how he was doing and everything. I asked them how they got my info and they said they called AQHA and they gave them my name. It didn't bother me but I can see some would mind. MInd you this was about 5 years ago. Things may have changed but the Association may be able to help you.
