I also have a mare with Vant Huttenest in her background .... this is Grand Oaks Blueberry Delight, her grandsire is Yashica Light Vant Huttenest, a Reserve National Grand Champion son of Orion.
My stallion, Coyote Winds Knockout, is a grandson of Searchlight Vant Huttenest(Irsul Light Vant Huttenest + Wilma Vant Huttenest) through his dam. His sire is a great grandson of Yang Light Vant Huttenest. I am not sure about my mares though, would need to check their pedigrees.
