Abstract: Records of the Nettie Fowler McCormick Biographical Association, formed in 1932 by Mrs. McCormick's children. Virgina Roderick was employed as secretary, and served in this capacity until 1956 when the work of the Association was completed and her biography, Nettie Fowler McCormick, was published. The papers are composed of Miss Roderick's correspondence with individuals, organizations, and institutions in the search for letters and information; recollections and interviews she obtained from hundreds of persons who had known Mrs. McCormick; and both original and copied letters relating to Mrs. McCormick, some of which Harold originally had in his files. Included also are copies of letters from Eldridge M. Fowler to Cyrus H. Jr. concerning Mrs. McCormick, and letters and notes that James G.K. McClure Sr. had collected for a memoir of Mrs. McCormick. In addition, there are copies of manuscripts and correspondence loaned by members of the Fowler, Spicer, Merick, and McCormick families, including Fowler family business papers dating back to 1802. Much genealogical and biographical information is filed, as are many clippings. Miss Roderick's own notes, memoranda, reports, working papers, and manuscript for her book are included.
