I am sorry you are having to deal with this mess up on the registration. It is possible for the stud owner to go back to the people they got him from and try to figure out who his sire really is? I have heard of people having these kind of problems and they were able to straighten it out. Of course it could get costly.
My advise would be to offer the people that bought the female pup from you some of their money back. That's about all you can do if they do not want to return their pup.
I am not sure what AKC will do about the previous litters that male sired. They may send out notices to those that have registered their pups. You might want to call AKC and ask them for advise.
