The Gilman family is the richest family in Sugar Maple Coast. They are also the oldest family in the area, with an unbroken line of descendants going back to when the town was known as Gilman Hill. The elderly Johnstone recently passed on the family company to his son Vincent and now spends his days doting on his new granddaughter. Vincent and his wife find themselves overworked at times between the pressures of careers and a new child.
Johnstone is the Governor of Sugar Maple Coast.
