Geraldine Chandler is Chas Chandler's daughter. She appears as a well-off young woman with a daughter named Tricia Chandler. She and her husband have been divorced and even then, still keep on fighting.
John Constantine interacted with her on three major occasions. The first one, when he warned the Chandler family to never name her baby after Chas' grotesque mother, second was when he helped Geraldine when her house was haunted by an old Japanese ghost, and the third was when John and Chas traveled to America to rescue Geraldine's daughter, who was in a permanent coma due to a demonic epidemic sweeping the globe.
