What is the parallel between present and past?

Ancestry is a heavily emphasized theme in Holes, and it goes hand in hand with the themes of fate and destiny. For each of the major characters, ancestry affects their surroundings, decisions, and even day-to-day life. Stanley ends up at Camp Green Lake, supposedly because of the misdeeds of his great-great-grandfather. The Warden’s life is devoted completely to the search for a treasure that her ancestors have been seeking for years after being cursed by Kissin' Kate Barlow. The conflicts of the past are of such consequence that they have the ability to seemingly transcend time itself by continuing through the generations and steering the destiny of the characters in the present-day narrative.
