As the dogs get closer to the parents, their names suggest they were not necessarily well informed breedings. It might help by starting to identify what your goals are with the dog you want and what traits will help you accomplish those goals. Then start looking for breedings that are likely to produce those traits. Looking at whether a pedigree has Czech or DDR dogs in it is of little value unless you know about the dogs in the pedigree and what they tended to produce.
I agree with Chip. The close up dogs don't have much in the way of titles (sire and dam don't appear to have any) and I'm seeing a lot of missing health certifications. What is it about this pedigree that you like? What are you looking to do with a dog? There are a lot of informed people on this site that can make breeder recommendations if you talk about what you're looking for.
