Kim Boniface—a member of one of Maryland's most prominent horse racing and breeding families—has died, according to reports from The Baltimore Sun and the Daily Racing Form. She was 51.
A daughter of Maryland industry icons J. William and Joan Boniface and an accomplished horsewoman in her own right, Boniface graduated from The John Carroll School in 1985. She competed as a champion amateur jockey, was actively involved in her family's Bonita Farm, and also went on to train Thoroughbreds. She sent out 567 starters from 1990 to 2018, compiling a 55-49-66 record with earnings of $1,393,608. Her last starter raced Nov. 5.
J. William Boniface, a past president of the Maryland Horse Breeders Association, bred and trained the late Deputed Testamony, who won the Preakness Stakes (G1) in 1983 and was the last Maryland-bred horse to accomplish that feat.
According to the Daily Racing Form, in addition to her parents Kim Boniface is survived by three brothers—William Boniface and his wife, Barbara; Kevin Boniface and his wife, Chris; and John William Boniface Jr.—and a sister, Bonita Boniface.
The family plans a private service. In lieu of flowers, they ask that contributions in Boniface's honor be made to the Maryland Horse Industry Foundation at P.O. Box 427, Timonium, MD 21094.
Cards and letters of sympathy can be sent to Bonita Farm, P.O. Box 366, Darlington, MD 21034.
