Abstract: Primarily monthly, quarterly, and annual statements of the income from real estate owned wholly or in part by Cyrus H. McCormick, Jr., or administered by him as trustee or executor. Reports on trusts for Mary Virginia McCormick, Stanley McCormick, Elizabeth Morss, and Sarah E. Stickney are included here, as well as reports on the estates of Elizabeth McCormick and Nettie Fowler McCormick. In addition, a small number of reports are given on properties owned entirely by Harold McCormick, Stanley McCormick (before his property was placed in trust), or Anita McCormick Blaine. Besides real estate reports, more general financial reports by the trustees of Mary Virginia and Stanley are also included, along with legal documents appointing administrators of Stanley's property in 1906 and 1909. Also present are reports on the McCormick Harvesting Machine Co., and material on the proposed additions to the Reaper Block in 1919.
