[3] Preserve's sire, Emilius, won the Derby in 1823 and went on to become a successful stallion at the Riddlesworth stud which was owned and run by Thomas Thornhill.

Apart from Preserve, Emilius’s best winners included Priam, Plenipotentiary, Oxygen, Riddlesworth (2000 Guineas) and Mango (St Leger) and he was British Champion sire in 1830 and 1831.

[6] Starting the 6/4 favourite against ten opponents she won the five furlong race by a length from Mr Mills' highly regarded filly Hester.

Ridden by "Old Bill" Arnull, Preserve tracked her rival throughout the early stages before moving to the front inside the final furlong and winning "cleverly" by half a length.

[8] Preserve's status as the leading English two-year-old filly of her generations was confirmed by the bookmakers who made her favourite for the Oaks Stakes throughout the winter break.

[10] A month after her win at Newmarket, Preserve was moved up in distance to contest the Oaks Stakes over one and a half miles at Epsom Downs Racecourse.

[13] On the following day Preserve had two engagements, beginning with the Verulam Stakes in which she was allowed to walk over the one mile course for a £100 prize after her opponents were withdrawn by their owners.

The descendants of Coturnix's sister Raker (1881) were exported to the United States where they have been successful to the present day: members of this branch of the family include Awesome Again, High Quest, Arts and Letters, Grindstone, Pass Catcher, Silverbulletday and the Melbourne Cup winner At Talaq.
