In Bar's case, pedigrees don't mean much. He is, after all, a gelding. No progeny for my boy.
But in my curiosity about him, about where he came from, I found this video of a nice little mare out of what looks to be Bar's half sister. (Her dam--Never A Question--seems to have had the same sire, Jett Sett Joe.)
In Lena's case, it means we could probably breed her and breed her well if we wanted a cutting horse baby. Or a baby at all. Which we don't. Okay, mostly we don't.
It's just part of my never-ending quest to figure just a little bit more out about my horses.
