Cheveley Park Stakes
Humble Duty was a grey filly bred at the Owenstown Stud at Maynooth in County Kildare, Ireland by Frank Tuthill. Her sire Sovereign Path, from whom she inherited her colour, was a top class miler who won the Lockinge Stakes and the Queen Elizabeth II Stakes. Humble Duty's dam, Flattering was placed in the Cheveley Park Stakes and was out of Flatter, a moderate race mare but a half-sister to The Derby runner-up Gay Time.
