Jonkheer Z is by the talented dressage stallion Jet Set D, who was the North Holland Champion Foal. He continued to impress judges with his temperament and athletic movement. Jet Set D was a striking stallion to watch in the dressage ring, who also showed a powerful jump over fences, and was known for the good usage of his back as well as his skillful technique. He produced multiple 1.50-1.60m horses including Piavera, Pasoa Dice, Sidney, and Ukkie who is an AES approved stallion. Jonkheer Z’s full brother Bariano van het Westleven is also a successful 1.60m horse. Their dam is Ulderina van Westleven by Skippy II who produced many Grand Prix showjumpers including Maloubet by Hap Hansen, Nikita de l’Aubry by Fernando Sarsola, My Blood, Teresa Blazquez, Marly du Beaumont, and Vincenzo Chimirri.
