Two of her sisters—Hannah and Guelma—married and eventually moved to Rochester, NY. Her sister Mary never married; she became a teacher and eventually gained the distinction of being the first female principal of the Rochester School District to receive equal pay for equal work. Mary kept house for their mother Lucy after father Daniel died. Guelma and Hannah both died of consumption (tuberculosis). Mary outlived all her siblings.

Susan’s brothers both emigrated to Kansas to work against slavery. Merritt fought slaveholders with John Brown. Daniel joined a vigilante band that raided slave plantations and freed slaves, connecting them with the Underground Railroad. Both served in the Union Army during the Civil War. After the war, Daniel served as mayor on and off for many years and published a newspaper. Merritt repaired and sold sewing machines. Like their father, both brothers died of heart conditions.
