Out on the west Texas range land of the Alamosa Ranch in Vega, Texas, Hall of Fame foundation stallion Mansfield’s Comanche roamed with a small band of mares. One of those mares — an unregistered Appaloosa known as Susan — produced a black-and-white son by “Comanche.” This colt spent his early years on the 60,000-acre ranch before being sold as a stallion prospect. The young stallion’s coat later faded to a blue roan with large, domino-like spots. In September of 1955, Harmon Scales of Lubbock, Texas, registered him as Double Six Domino.
Double Six Domino’s breeder, Jack Mans-field, practiced intense linebreeding with his herd. While many of Jack’s horses predate the Appaloosa Horse Club, unofficial records suggest Double Six Domino is the result of breeding Mansfield’s Comanche to a Mans-field’s Comanche daughter. An article by Ron Stull, in the February 1966 issue of Appaloosa News, also gives the mare, Juan-ita, as Susan’s granddam on the bottom side. This gives Juanita at least three places in Double Six Domino’s pedigree. His grandsire, though on record as the unregistered Dr. Howard, is said to be the Thoroughbred remount stallion Dr. Howard in the Febru-ary 1966 issue of Appaloosa News.
Double Six Domino’s various owners used him purely as a breeding stallion and never collected national points in the show ring. Instead, the stallion impacted the App-aloosa breed by siring 250 registered foals which were, in turn, used for breeding, show-ing and racing. Double Six Domino earned the National champion get of sire title in 1970 and placed in the top five for get of sire in 1960, 1962 and 1964. He sired 17 race starters who earned a combined $20,766.35. Three of his get showed while the points system was in effect, earning three bronze medallions, one register of merit and 23 points.
