I should also point out that it’s been said that not a single WB line traces back to a non-Blood stallion. If you have ever gone back in pedigrees to the beginning of the tail male, you’ll find that except (possibly) for Farn that statement would seem to be true. The East Prussians were particularly fond of the offspring of the TB mare Pocahontas from the early 1800s and used something like six of her offspring in their breeding.
And that is the point. The Traks were very closely tied to Tb’s at the early stages. All the famous stallions go back to mainly Tb, Arab or British bred lines. They did have regional influence but the vast majority of horses and the horses that most Traks are line bred to are Tbs. My Trak, Hanoverian both have the same TB influence though TB, Holsteiner and the Trak ancestors. Having done pedigree work, I realized that the Wb’s are not a random group of German horses but instead where a tight knit group of hand picked horses that formed a registry. Not unlike how most breeds including the Tb, are formed.
This is a hugely influential sire and the pedigree usually ends with a Tb, Arab or a British horse of unknown pedigree like this one http://www.sporthorse-data.com/d?i=158946.
Another stallion used http://www.sporthorse-data.com/d?i=218459, very modern looking for 1880.
I think people need to put horse in context of the time they lived. Most people farmed and a horse needed to earn a living. If they were not carrying soldiers, they needed to be working. The area I grew up in used horses two generations ago (from me) for everything. They rode them and worked with them. Often it was the same horses unless you were very well to do. The fact that people used the horses for farm work doesn’t detract from their other abilities.
