Tranquil

Tranquil (1920 – October 1938) was a British Thoroughbred racehorse and broodmare. She showed considerable promise as a two-year-old when she won one race and finished second in the Gimcrack Stakes. In the following season she was one of the best horses in Britain, scoring classic victories in the 1000 Guineas and St Leger Stakes as well as winning four other races including the Jockey Club Cup and Newmarket Oaks. She won once in 1924 before her racing career was ended by injury. She made no impact as a broodmare. Background Tranquil was a "big, raking" bay mare bred in England by her owner Edward Stanley, 17th Earl of Derby. During her racing career she was trained by George Lambton at the Stanley House stable near Newmarket, Suffolk. Her sire Swynford was an outstanding racehorse who won the St Leger in 1910 and the Eclipse Stakes in the following year. He was even better as a breeding stallion with his other offspring including Blandford, Saucy Sue, Challenger and Sansovino. Tranquil's dam Serenissima was an exceptional broodmare whose other descendants included Sickle, Hyperion, and Pharamond. Racing career
