He came to Princeton from Kent School, where he captained the football team, played hockey, participated in the Drama Society, and was awarded the Drama Prize. At Princeton Denny majored in English, was a member of Cannon Club and played IAA football, hockey, and baseball for “The Gun.” He participated in the Campus Fund Drive junior and senior years.
Denny spent much of his youth in St. Croix, where his family had a business and a horse farm. Following a stint in the Army, he returned and worked there for about 10 years, returning to the States in 1975. He went to work in the Savannah office of Colonial Life and Accident Insurance Co. and remained there until ill health forced his retirement in 2020.
Denny had a lifelong love of horses, especially the Paso Fino breed his mother had raised in St. Croix. In 1997 he bought a 20-acre farm and raised and bred Paso Finos, a breed imported to the Caribbean from Spain by Christopher Columbus. The name translates as “fine step” and, according to the Georgia Paso Fino Association, “their four-beat lateral gait is exclusive to this breed and is the key to their unequaled smoothness in the horse world.”
Denny and his wife, Margie, were very active in the association. Their Santa Cruz Farms included 18 of their own horses, plus some they boarded for others.
Denny is survived by Margie, daughters Twyla Mancil Jones and Diana F. Rouses, sons Matthew Mancil and G. Richmond Mancil, and six grandchildren.
