Kepley's legacy was not in the practice of law, but rather in her passion for
temperance and
women's suffrage. Her temperance crusade centered around her establishment of the Band of Hope, a youth-oriented temperance group, which focused on educating the youth of the
Effingham, Illinois, area concerning the hazards of alcohol addiction. In conjunction with her organization, she also published a monthly temperance newspaper entitled
The Friend of Home which openly attacked the dram shops (saloons) and their patrons. In 1897, an angered saloon-keeper's son broke into Kepley's home and attempted to shoot her with a gun, but missed and shot one of her dogs in the foot. Kepley's association with nationally known women's movement icons
Frances Willard (of the
Woman's Christian Temperance Union or WCTU) and
Susan B. Anthony (co-founder of the
National Woman Suffrage Association) gained Kepley national recognition in these organizations. Frances Willard attended a WCTU rally in Effingham at Kepley's request. Upon the death of her husband Henry in 1906, the bereaved Ada moved to the Kepley's farm between
Watson and
Mason, Illinois (now known as Wildcat Hollow State Forest). There, Kepley wrote her autobiography, entitled
A Farm Philosopher, A Love Story (since edited and re-published), which she published in 1912. The book was printed by Worman's Printery in Teutopolis, Illinois. Of the land that is now Wildcat Hollow she writes ==Poverty and death==
