 After arriving in De Smet, Caroline and the Ingalls family lived in the home of the local surveyor as well as a store in the downtown area, before homesteading just outside town on a farm by Silver Lake.When the Ingalls family sold the farm due to a persistent pattern of dry years, Charles built a home for them on Third Street in De Smet, known later as "The House That Pa Built".Following her husband's death from heart disease in 1902 at age 66, Ingalls and her oldest daughter, Mary, remained in the De Smet house, renting one of the rooms for extra income.
