Georgina Gordon, known as Nan, acts as governess and primary caretaker for Marnie during her parents' frequent travels abroad. She resides with Marnie at Marsh House, managing her care alongside twin maids Ursula and Ella De Vil. Nan subjects Marnie to persistent physical and psychological abuse, including roughly yanking her arm and aggressively brushing her hair to inflict pain. She also verbally abuses Marnie, explicitly calling her "nothing but trouble." During a formal dinner party hosted by Marnie's parents, Nan attempts to enforce Marnie's bedtime. Marnie and her guest trick Nan into entering Marnie's room and lock her inside. After the party and another departure by Marnie's parents, Nan disciplines Marnie for her actions. Nan's presence concludes when Marnie moves from Hokkaido to Sapporo after marrying Kazuhiko. The ultimate fate of Nan and the maids remains uncertain; they were presumably dismissed by Marnie's parents and potentially arrested for abuse. A less substantiated alternative suggests they may have died by lightning strike. Physically, Nan is a short elderly woman with grey hair. She wears a purple iromuji kimono with a tan nagoya obi and traditional Japanese geta sandals.
