Query: Intimate recollections of the Lincoln White House

Although this volume comes from the memories of someone familiar with the Lincoln White House and who became a close friend of Mary Todd Lincoln, it must be read cautiously. For example, despite the book's basic authenticity I find its account of Stephen Douglas's love for young Mary Todd and her jilting of Lincoln implausible despite Keckley's claim that she got the story directly from Mary Todd Lincoln and Anson Henry (a close friend of Abraham and Mary, who was a matchmaker encouraging their romance). Possibly some errors might be attributed to one or more literary assistants who helped compile the book. If a reader needs to be certain a about a particular statement, comparison with other sources is wise. Still, the volume will be valuable to anyone interested in firsthand impressions of the Lincoln White House.
