No way in hell you'll get the name of the person it was made for or sold to. That's a huge violation of privacy laws. Unless the frame is extremely unique or the rider's name or team name are painted on the frame, you are out of luck on finding that info.
Please point me to these "privacy laws" that exist for ownership history on a bicycle. I sell cars and unique/rare items with ownership history all the time! High end auctions do that all the time!
