Jessica Stark's Father
Jessica Stark's father and role model was a tough man of hard work, honesty, integrity and confidence; these were the traits Jessica took from him as she grew up. Working on the ranch Jessica's father taught her about taking care of, raising, profiting from and training the many pokemon that lived in the immediate area. Apparently he still lives on the ranch Jessica comes from, taking care of it alone in her absence.
Jessica's Father's pokemon are currently unknown, though they're confirmed to exist.
