It’s really fun to go down a rabbit hole with the WBs, and see where they emerged from, too, and how some of the lines go back many generations, and some get new blood interjected in more recently. Obviously the TBs are super important, but there are so many other things mixed in. It’s fascinating.
I am supposed to be grading so instead I was just spending some time with the pedigrees for my two guys- neither has any TB until several generations back, but there is a lot going on when you get there and then dig farther! Both have a TON of Selle Francais, so then they go back to French Trotter and there are the half-bred SF, and then the TBs start to show up.
My older boy has Ladykiller and Chanteur on bottom several generations back, and a whole slew of “halfbred” on top- half TB, half something else. One of those is Debuche- he was built like a mack truck, much like my guy, and had Anglo-Norman on top. It’s very cool. https://beta.allbreedpedigree.com/ct-quantum-Cr8VFLOo/pedigree
For my little guy one has to go back a ways to find the TBs, like Furioso, but again, this is so cool to dig through. Some more Anglo Normans (he’s got Jus de Pomme!), Anglo Arabs, etc. It’s also fun when there are pictures and you can try to see traits, or even find videos of close relations. https://beta.allbreedpedigree.com/tatabra-goliat-U7iDf5Ss/pedigree
