It is a shame that the breeder wasn't up front regarding the litter pedigree.
It is interesting though - when does a dog become pure show cocker - how many generations must be pure before they can be called a pure show cocker. For my two the FTCH is 4 generations back. I know that labradors (black) have Gordon Setters crossed into their lines many generations ago (very long time ago) and on very rare occassions you can find a black labs with tan eyebrows.
Both Roly & Misha's GGG grandparent on their dad's side is a FTCH, though they are both show cockers in looks -- best of both worlds really for me, both have cracking personalities and not any health problems, both very robust and have been very good to train (I'm biaised I know
). I got them both as pets and for agility and my main concern was that they were strong and healthy. I met both mum & dad for both dogs who were also lovely dogs, very friendly and very sweet and all the parents were health tested. Since I wasn't going to be going into the world of showing the FTCH hasn't mattered to me and the dogs have turned out great - I would go back to the same breeder in a minute if I was after a puppy.
