Although royalties from the "Little House" books helped provide for the Wilders, their daughter helped support them until the mid-1930s. Eventually their efforts at Rocky Ridge during the 1930s and 1940s, along with the book royalties finally provided a secure enough income to allow them to attain a financial stability they had not known earlier in their marriage. When they were first married, Wilder's wife had helped contribute to their income by taking in occasional boarders, writing columns for a rural newspaper, and serving as Treasurer/Loan Officer for a Farm Loan Association. Their daughter lived with the Wilders on the farm for long periods of time, seeing that electricity and other modern updates were brought to the place, even having an English-style stone cottage built for them, and then taking over the farm house for about ten years.
