Joseph Dennison, who for several years has taken care of Byron McClelland’s breeding stock at Lexington, Ky., has become violently insane. His insanity was caused by the accident to McClelland’s valuable yearling colt by Longfellow dam Sallie McClelland. The colt broke its left hind leg and had to be shot. Dennison became imbued with the idea that he was to blame for the loss of the colt, and has thought and talked about nothing else since the accident. He went into town and acted so queerly that he was locked up and will be sent to the asylum.
Byron McClelland was a succesful owner and trainer of horses. One of his horses, Henry of Navarre, won the Belmont in 1894, and another, Halma, won the Kentucky Derby in 1895.
Longfellow was inducted into the Thoroughbred Hall of Fame. He’s known as the King of the Turf. Sallie McClelland was also a winning horse. So it’s likely that any offspring of theirs would have had good potential for winning races and later becoming a profitable stud.
Unfortunately, it’s much easier to find the pedigrees of the horses than it is to find Mr Dennison. I don’t know what happened to him. I suppose today he would have been called “distraught” and possibly had therapy.
