James E. Keet died in July 1900. The St. Louis Republican took note of his passing: "James E. Keet, one of Springfield's most prominent businessmen, died today. He was president of the National Exchange Bank, president of the Keet-Rountree Wholesale Dry Goods Company, and a moving spirit in a number of other [illegible] concerns."
In his 1895 will, James stated that he had complete "faith and confidence in [his] wife, Kate," and believed that she would ensure the welfare of their children; therefore, he left the entire estate to her. In a codicil, written barely a month before his death, he bequeathed one thousand dollars to each of his siblings.
Katherine Holland Keet lived in the house until her death in 1920. James and Katherine's daughter, Katherine E., was already living there with her husband, Claude McElhany. Claude died in 1956 and Katherine E. remained in the family home until her death in 1983.
