Stockwell (1849–1870) was a British Thoroughbred racehorse and a Leading sire in Great Britain & Ireland seven times; he was second on the sires' list a further four times during a 14-year period. Breeding Stockwell was foaled in Stockwell, England, at the stud farm of William Theobald. His sire, The Baron was a successful racehorse and sire. His dam Pocahontas was a roarer – a trait never demonstrated in Stockwell himself, but passed to several of his descendants. Pocahontas later also produced the successful sires, Rataplan and King Tom. The chestnut was not a particularly pretty horse; he was described by one turf writer as "the very incarnation of ugliness," possessing a plain head with a slight Roman nose and hindquarters like a carthorse. He had good feet, strong legs and was very powerful, however, giving him the ability to carry high weights. Although a poor mover he was very fast; his speed made up for his terrible temperament, which was considered "a bit savage". Stockwell stood over 16 hands high with a stripe on his nose, a sock on his off (right) hind leg, another mid-cannon sock on his near (left) hind leg and Bend-Or spots on his coat. Although the colt was thought to be "over-large," Brownlow Cecil, 2nd Marquess of Exeter purchased the yearling for 180 sovereigns, with the contingency that he would pay £500 more if Stockwell won The Derby.
