Mary Custis Lee lived here until the center section and second floor of the house were finished in 1818. The room then served as a guest chamber. Years later, some of the Lee children stayed here during the
family's travels to Robert's many army postings. Daughter Mary Lee slept here when the rest of the family was stayed in St. Louis in the late 1830s while Annie and Agnes Lee encamped in this room during their parents' time living at West Point.
