Rockingham was a British Thoroughbred racehorse and sire best known for winning the classic St Leger Stakes in 1833. After finishing fourth on his only appearance as a two-year-old, the colt was undefeated in three starts in 1833, winning the St Leger in the harlequin colours of Richard Watt and taking the Doncaster Cup against older horses in the same week. Rockingham remained in training for three further seasons, winning the 1835 Goodwood Cup, four King's Plates, and three consecutive renewals of the Brighton Gold Cup. He was retired from racing for a brief stud career, but had little success as a sire of winners.

St. Giles was a British Thoroughbred racehorse and sire. In a career that lasted from October 1831 to July 1835 he ran eleven times and won five races. After showing little form as a two-year-old, he made marked improvement to win his first three races of 1832, culminating with a highly-controversial success in The Derby. His only subsequent wins came in two minor races in 1835 and he was eventually sold and exported to stand as a stallion in the United States.
