Correspondence, personal ephemera, diaries, scrapbooks, and financial and estate documents of individual members of the Marsh, Roberts, Mack, and related families. Of note is correspondence of Daniel Elston, early Chicago settler, and legal papers of his daughter Blanche and her husband Robert R. Clark. Both Clarks died in 1907, and Blanche, who lived a few months after Robert Clark, had inherited her father's considerable fortune. After Blanche's death, her will was disputed by her brother Daniel Jr. and his wife Alice, who were left nothing of the Elston estate. There is also a significant amount of fictional writing and intricate pen and ink drawings by George R. Roberts, much of it relating to Norse mythology. Roberts also kept humorous and detailed journals of his travels as a child and with his wife Katherine Marsh Roberts.
