Dungannon (horse)

Dungannon, (aka "Duncannon"), was a thoroughbred racehorse owned by the tobacco planter and horse breeder George Hume Steuart (1700–1784), who imported the horse from England to race against his rival, Charles Carroll of Annapolis (1703–1783). Dungannon won the Annapolis Subscription Plate, in May 1743, the first recorded formal horse race in colonial Maryland, and the second oldest in North America.
