I suggest you go to
American Kennel Club - akc.org and look up bull terrier breeders, then contact them. Many of them have websites as well. They may be familiar with some of these names, and most of them have breed history magazines and books that they use for research and reference all the time.
Do you have the name of the breeder of your dog? (I'm assuming you have a dog now that you're trying to research). Do you have any registration papers with the dog?
Even if you have jsut a litter number, you can get the breeder's name from the AKC.
Good luck. Not knowing more about your specific situation, I don't know what else to suggest. Try googling those dog names to see what comes up.
