Great Dane Puppy Wanted

I would like to trace the lineage of Great Danes in Jamaica. I have 8 pure bred puppies for sale, although I am not a breeder. I've been able to trace the lineage of the father of my puppies but not much on the mother. The only people I know of that have bred G.D's are ABC McDonald, Mark Harris, Andrea Andrade and Joseph Issa. If you know of anyone else could you please give them my contact info and ask them to give me a call, Rosemarie Levy 399-4940. Thanks in advance
