MESSENGER

(foaled 1780), racehorse who, though a Thoroughbred who sired many successful Thoroughbred (flat) racers, was most important as the foundation sire of the Standardbred (harness racehorse) breed. A son of Mambrino and grandson of Matchem, he was foaled in England but was taken to Philadelphia in 1788. His descendants became known for their trotting ability, and his great-grandson Hambletonian is the ancestor of most modern trotters.
