Godolphin Arabian
Although today the majority of Thoroughbred horses’ sire lines trace to the Darley Arabian, several famous North American horses of the past trace their sire line back to the Godolphin Arabian. These include Seabiscuit, Man o' War, and War Admiral. Today, the sire line is primarily supported by descendants of Relaunch and his son Cee's Tizzy through dual Breeders' Cup Classic winner Tiznow.
