In praise of dissertations

In a previous Vita Brevis post, I sang the praises of tax lists as useful sources of information for family history research. Today’s post focuses attention on another valuable but underutilized research resource: unpublished doctoral dissertations.

Since the 1960s, Ph.D. candidates at U.S. universities have written a surprisingly large number of dissertations on the histories of individual American towns, ranging from the early settlements of colonial New England and other regions to nineteenth-century midwestern farming communities. Invariably based on exhaustive research in primary historical records, these in-depth “community studies” usually include large quantities of detailed statistical and descriptive information about the local inhabitants – their economic activities, landholding patterns, ethnic and religious compositions, social structures, and more. Some include a biographical list of early town residents, with male residents identified by occupation. In addition, every dissertation has an extensive bibliography listing additional sources of historical scholarship about the community.

[These] in-depth “community studies” usually include large quantities of detailed statistical and descriptive information about the local inhabitants…

In researching the lives of the first two generations of my family in America for a recent family-history book project, I drew heavily from unpublished dissertations on the early Massachusetts Bay towns of Ipswich and Andover.[1] The massive amounts of quantitative and descriptive data contained within them enabled me to place my ancestors in a social and economic context – as artisans, as “commoners,” as landowners, as members of extended “middling”-level family networks, etc. – that proved to be much more detailed and historically nuanced than would have been possible using only published sources. In the end, the dissertations were so valuable to my research that in one chapter alone I cited them in nearly half of the 107 endnotes.

A keyword search of town names in the “ProQuest Theses & Dissertations” database ( – the most comprehensive online catalog of U.S. doctoral dissertations – may prove equally worthwhile for other family history projects. Full-text electronic copies of most dissertations can be obtained directly from ProQuest or through a nearby university research library.

Greven, Jr., “Four Generations: A Study of Family Structure, Inheritance, and Mobility in Andover, Massachusetts, 1630-1750” (Ph.D. dissertation, Harvard University, 1964).

A small percentage of dissertations – including the Greven dissertation cited above — have been published as monographs. Almost inevitably, however, substantial portions of their quantitative data fell victim to the editor’s red pencil, so that the original dissertation version remains well worth reading.

  1. Michael,
    You are truly a wealth of interesting information. I love the academic rigor and insights you have shared on this site. As both an historian and genealogist I also want to provide the proper cultural context to my ancestors often found in town histories
    Perhaps NEHGS has or will add these dissertations to its collections?

  2. How did you access Proquest? The require a log-in, apparently, preferably, through a library.

    1. A reference librarian at a public, school, university, or other institutional library should be able to help you gain access. In our current covid-world environment — with most libraries closed — this unfortunately may not be feasible at the moment. But hopefully, order (and safety) will eventually be restored, and we will again be able to return to normal processes..

  3. This so falls under the category of “you found it where?” In 10 years of reading genealogy blogs I’ve never seen this topic before. Thank you so so much

  4. What a great idea! Years ago I was contacted by a graduate student writing one about some of my colonial ancestors…he was supposed to send me a copy but he never did. Maybe I can find it this way! Thanks.

  5. I love this! Never thought of it even though I’ve just retired from a university and have for 10 years freelanced editing doctoral dissertations. My retirement goal is to finally get around to writing the genealogies, so I’ve been looking at ways of rounding out the stories with details about how my ancestors lived. This will definitely help!
