During her 20-year marriage to Thomas Mellon Evans of Pittsburgh, Betty Barton Evans shared his passion for breeding thoroughbred horses.
In 1981, their efforts succeeded when Pleasant Colony won the Kentucky Derby and the Preakness. The couple ran Buckland Farm, a 495-acre ranch in Gainesville, Va., which Mr. Evans, a wealthy financier, purchased in 1956.
Mrs. Evans, who was 89, died Tuesday at her home in Greenwich, Conn. A native of Rockhill, S.C., she married Mr. Evans in 1977. He died in 1997.
The couple also bred horses on a 360-acre farm in Lexingon, Ky. Other successful horses were Pleasant Stage, which won the 2-year-old filly championship after winning the Breeders' Cup Juvenile Fillies race at Churchill Downs in 1991. Dance Colony won the 1989 Adirondack Stakes at Saratoga. Cherokee Colony won the 1988 Flamingo Stakes at Hialeah Park Race Track in Hialeah, Fla.
During World War II, Mrs. Evans lived in Washington, D.C., and worked for the Coordinator of Information, a forerunner of the Central Intelligence Agency. There, she met William Farnsworth Loomis of Tuxedo Park, N.Y. The couple married after he was deployed to China. Later, they raised three children in Connecticut.
Mrs. Evans collected furniture, paintings and wine and loved dogs. A memorial service will be held at Round Hill Community Church in Greenwich, Conn., at 11 a.m. March 9.
