Touchstone (1831–1861) was a British bred Thoroughbred racehorse and a leading sire in Great Britain and Ireland on four occasions. He was owned and bred by Robert Grosvenor, 1st Marquess of Westminster, who bought him for the low price, at the time, of 600 guineas at the insistence of his chief stud groom Mr. Thomas Nutting.

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.
