The historian Ruth Crocker has studied how Sage provided in her will for distribution of more wealth: her legacy had fifty-two equal parts. Nineteen named educational institutions received one part, or about $800,000 each. She made larger bequests to the following of $1.6 million each: the Emma Willard School, the Woman's Hospital, the Children's Aid Society, the Charity Organization Society, the Metropolitan Museum of Art, the American Museum of Natural History, and Syracuse University. She also provided large donations in her will to a variety of churches, missions, and other religious causes.
