Rose was ever concerned about the plight of Native Americans and much of her work was devoted to educating them, caring for their sick, and working against alcohol abuse. Finally able to retire from her administrative duties, Mother Duchesne evangelized the Pottowatomies in the Rocky Mountains at age 71, and taught young girls of the tribe. This work, however, lasted but a year as she was unable to master the Pottowatomi language. She was known to the tribe as "Woman-Who-Prays-Always".
