Corrie’s older sister. As a child, Corrie frequently contrasts Nollie’s composure and physical poise to her own shy nature and plain looks; however, she admires her sister’s attributes rather than resenting them. Since girls cannot win university scholarships and the family can’t afford tuition, Nollie attends a teacher training program, where she meets her husband, Flip von Woerden. Nollie and Flip live close to the Beje and have several children, including Corrie’s favorite nephew, Peter. During the occupation, Corrie enlists Nollie into hiding several Jews in her house. Eventually, Nollie’s activities are discovered and she is arrested and held in prison for several weeks before Corrie manages to get her medically discharged. She is detained a second time when the Gestapo arrests Corrie and the rest of the family, but she is released in Haarlem, rather than being sent to a concentration camp.
