Applying the Genealogical Proof Standard to Intellectual History

This project applies the Genealogical Proof Standard (GPS)   to the reconstruction of Mary A. Douglas’s personal and intellectual development, and her social positioning within Progressive Era reform networks. Traditionally used in family history, and the author is unrelated to the subject, GPS provides a rigorous evidentiary framework particularly suited to cases involving fragmented archives, reputational erasure, and name changes.

The five elements of GPS are operationalized as follows:

  1. Reasonably Exhaustive Research
    Research includes contemporaneous newspaper coverage of the 1913 confinement case; verified 1916 and 1917 publications in Book News Monthly, The Forum, and Forbes; the 1942 Jarvie Service case record; and the 1948 New York death certificate. Archival repositories identified for further inquiry include the Lilly Library (Sinclair manuscripts), Otsego County Clerk’s Office, Otsego County Historical Society, Columbia University Archives, and denominational archives connected to Jarvie Service; Sullivan County Historical Society; Sullivan County Sheriff’s Office; American Society for Psychical Research (in person visit), FOIL requests to the Sullivan County District Attorney’s Office and County Clerk, Otsego County Clerk’s Office, and to the Federal Bureau of Investigation, Village of Monticello, and Town of Thompson.
  2. Complete and Accurate Source Citations
    All claims are tied to identifiable publications or archival records. 
  3. Analysis and Correlation of Collected Information
    The transition from Adelaide M. Branch (1913 press coverage and poetry publication) to Mary A. Douglas (1917 essayist) is analyzed as a documentary identity shift supported by dated publications and vital records.
  4. Resolution of Conflicting Evidence
    Occupational designations such as “author” appear in census data -- a skilled writer, she authored published magazine essays and short stories, and later secured employment as an assistant author and researcher.
  5. Soundly Reasoned, Coherently Written Conclusion
    The conclusion supported by current evidence is limited and precise: Mary A. Douglas was a nationally published essayist in 1917 whose documented associations place her within Progressive reform networks.

By importing genealogical evidentiary discipline into intellectual history, this study avoids narrative inflation while still restoring agency to a historically marginalized subject.
