Snow Knight was bred by J. A. Claude Lilley, a textile manufacturer and the proprietor of Quarry Stud on Duffield Bank in Makeney, Derbyshire. Lilley had owned and raced Pretendre, sire of the 1971 Kentucky Derby and Preakness Stakes winner, Canonero II. Snow Knight's dam was Snow Blossom, a daughter of Flush Royal, winner of England's Great Yorkshire Stakes and the Prix Noailles in France. His sire was the speedy runner Firestreak who had been owned by Canadian lawyer Neil F. Phillips, whose wife Sharon purchased Snow Knight at auction as a yearling for £5,200.
