Carol Lush, a prominent sport horse and pony breeder, lost her 2 1/2-year battle with ovarian cancer on July 19 at her home, Maple Side Farm in Quakake, Pa. She was 58.

Mrs. Lush’s whole adult life was devoted to her passion for breeding good horses. She began her program in the 1970s by putting together a broodmare band of exceptional individuals. Before the days of the Internet, Mrs. Lush became part detective, making exhaustive searches and tracking down Thoroughbred racing mares with top sport horse jumping pedigrees.
