July Stakes
Jealousy (who was originally called Relapse) was a bay filly foaled in 1854. She was sired by The Cure, who won the Champagne Stakes in 1843. As a sire he also produced the July Stakes winner Dictator and Ebor Handicap winners El Hakim and Underhand. Jealousy's dam was Jewess, a daughter of Jacques. She was trained by Charles Balchin.
