Certainly I am familiar with all these - Klassic, Herminia, Adebanke, La Reina, Kazor, Bupe, Fogo, and All Square.
Some that you quote are kennel names. Some are individual dogs. Bupe is certainly Bupe Itapuca, born in Brazil (bred by Savio Steele) and living in Russia. Fogo, I would bet, is Fogo Itury Puzzle Itapuca from the same kennel but also in Russia. Herminia Itapuca is from the same kennel, and shares a sire with many Adebanke's. Which gives you that tie-in.
I don't have the parents - but Dietburg of Fei Jack FCI - the FCI indicates she is from a kennel which includes FCI in the name of the dogs. If you can give me HER parents, I can check it for you. Polish bred dogs very often have this inclusion.
I have two Belaxe in the database which have appeared in China. Both are from a litter by Fogo out of Herminia. Chinatop Thunder MIGHT be a littermate and if you think he is, I will add him immediately.
The coding you refer to is / are registration numbers from different countries.
