 Edward Simms imported the famous French horses Prince Palatine and Negofol to stand at stud at Xalapa Farm.Among his offspring, Negofol sired 1917 Belmont Stakes winner Hourless and the 1925 Preakness Stakes winner Coventry.Over the years, best known among the horses bred at Xalapa Farm were graded stakes race winners such as Suave Dancer who in 1991 won the Irish Champion Stakes and Prix de l'Arc de Triomphe, and “blue hen” broodmare Hildene who was sold to Christopher Chenery in 1939 following Edward Simms' death.
