ETHNIC IDENTITY AND DIET IN THE CENTRAL ILLINOIS RIVER VALLEY By Ryan Maureen Tubbs A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Anthropology – Doctor of Philosophy 2013 ABSTRACT ETHNIC IDENTITY AND DIET IN THE CENTRAL ILLINOIS RIVER VALLEY By Ryan Maureen Tubbs This dissertation investigates how ethnic identity is formed and manipulated following a migration. To reach this end, food choice is examined as a deliberate cultural symbol used to negotiate ethnic identity. This research utilizes a case study which explores food choice following the pre-Columbian migration of an Oneota group into west-central Illinois. Following a migration, social identity is often renegotiated and a new ethnic identity may be formed. Diet serves as an effective vehicle for manipulating individual and group identity; therefore, examining changes in food choice following a migration presents information regarding migrant population’s physical and cultural interactions with their new environment (Fishkin 2005). The migration of Oneota people to west-central Illinois (ca. A.D. 1300) presents a unique opportunity to assess Oneota subsistence, and by proxy ethnic identity, in an area that is optimal for maize agriculture (Conrad and Esarey n.d..; King 1993; Santure et al. 1990). Archaeological investigations have revealed evidence for conflict, cohabitation, and cooperation between the migrant Oneota group and local, maize-reliant Middle Mississippian people. This project seeks to reveal if and how the Oneota altered their traditionally diverse diet to manipulate their ethnic identity as they interacted with their new neighbors. Two broad research questions were generated which focused on diet: was the Oneota diet in the central Illinois River valley different from the Middle Mississippian diet in the area, and did ethnic identity, among social categories, have the strongest impact on the west-central Oneota diet? To explore these questions, Morton Village (IAS 11F1), a Bold Counselor Oneota habitation site, and the associated mortuary site, Norris Farms 36, were chosen as the Oneota sample. Orendorf (IAS 11F107), a nearby Mississippian habitation and mortuary site, was chosen to represent local Middle Mississippians. Analysis of stable isotopes from seventy-five human bone samples from each of these two sites allowed for the comparison of consumed diet 13 15 at Morton Village and Orendorf. The δ C and δ N values of the samples were examined as part of an intersite analysis and the isotope values from Norris Farms 36 remains were further explored as part of an intrasite analysis. The intersite analysis demonstrated differences between diets at the two sites, with 13 15 significantly lower δ C values and generally higher δ N values at Norris Farms 36. This indicates that there were deliberate differences in food choice between the two sites which may have been used by the inhabitants at Morton Village to signal their ethnic identity to local populations. The intrasite analysis revealed a relatively large amount of variation. The lack of homogeneity at Norris Farms 36, even within groups based on sex and age, indicates that there was not a homogenous ethnic identity at Morton Village that was prioritized over other available social identities. In addition to shedding light on Oneota subsistence, this study demonstrates how the investigation of diet can reveal valuable information about ethnic identity and social interactions. In light of the evidence for positive and negative interactions in the area, the results of this study suggest that the inhabitants at Morton Village used food choice in a deliberate manner, likely using diet to invoke specific identities on a situational basis.

I would like to thank the Illinois State Museum for granting me access to the Norris Farms 36 and Morton Village collections. I also would like to thank Dr. George Milner for hosting me at Penn State while I worked with the Norris Farms 36 collection and Dr. Michael Wiant for hosting me at Dickson Mounds Museum while I worked with the Morton Village collection. I would also like to thank the Upper Mississippi Valley Archaeological Research Foundation and Dr. Larry Conrad for granting me access to the Orendorf collection. I’d like to thank Dr. Dawnie Steadman for hosting me at Binghamton University while I worked with the Orendorf collection. Dr. Dawnie Steadman was also incredibly helpful and patient as she listened to my ideas and encouraged me during the early stages of developing this project. I was able to travel to collect my samples through the support of the Food, Nutrition, and Chronic Disease Research Fellowship awarded by the Graduate School at Michigan State University. I also received financial support for trips to Morton Village from the Michigan State University’s Department of Radiology. My graduate school classes were funded in part by the Jacob K. Javits Fellowship from the United States Department of Education. I would like to thank all the members of my doctoral committee, Dr. Jodie O’Gorman, Dr. Norman Sauer, Dr. Lynne Goldstein, Dr. Todd Fenton, Dr. Mark Schurr, and Dr. James Rechtien. This dissertation could not have been completed without the help and support of the entire committee. Some members went above and beyond and for that I am truly grateful. vi Dr. Jodie O’Gorman was incredibly helpful throughout the process and I cannot thank her enough. Early on, she forced me to articulate my research interests and then sent me on a road trip to sites and museums to discover how I could develop my research interests into a viable project – quite possibly the most important step in this entire process. She was supportive and patient through the many years I spent on this project and I hope that I have many opportunities to work with her in the future. Dr. Norm Sauer was very supportive throughout graduate school and I appreciate all of his help. Dr. Todd Fenton was a good cheerleader and Dr. James Rechtien was very helpful as an outside reader. Dr. Lynne Goldstein was an incredible help in navigating both graduate school and academia as a whole. I have learned a great deal about mortuary analysis and the field of Anthropology from working with Dr. Goldstein and highly value her advice. Dr. Mark Schurr, from the University of Notre Dame, was an invaluable resource. He put an incredible amount of work into helping me develop my understanding of stable isotope analysis. I am extremely grateful for his time and patience. I would also like to thank Dr. Schurr for allowing me to process my samples in his lab and his student assistants for their help with the demineralization process. Additionally, I’d like to thank the University of Notre Dame’s Center for Environmental Science and Technology for assisting me with the isotope ratio mass spectrometer and for being all around great hosts. I would like to thank Michigan State University’s College of Human Medicine and Department of Radiology for keeping my family fed for the last seven years. I have truly enjoyed the opportunity to teach anatomy and appreciate the support of my colleagues while I have worked to finish my Ph.D. vii I am also grateful for the support and friendship of Drs. Mary Megyesi, Lindsey Jenny, Michael Koot, Wendy Lackey-Cornelison, and Jered Cornelison. Upon my graduation, we have officially all made it! Thank you for your advice, commiseration, and encouragement. I am proud to call you all my colleagues. In addition to my physical anthropology cohort, I’d like to thank all of the friends I made during graduate school. I feel very blessed that this list is too long to include here but please know that it was our get-togethers that kept me sane and I appreciate all of the many laughs we’ve shared. Likewise, I am blessed with the best friends and family any one could ask for. Thank you all for everything you have done for me along the way, whether it has been to forgive me for my lack of time or to force me to take a needed break. A special thank you to my dear friend Mark Roosien who has read my entire dissertation – and parts of it more than once! I would like to thank my awesome parents, Barbara and Derek Tubbs, for encouraging me to pursue my dreams. My parents, along with my amazing sisters Regan and Rory, assisted me in so many ways throughout this process but I am particularly grateful for their emotional support. My parents and Regan also deserve special recognition for their help with Dean – it truly takes a village to raise a child, particularly while writing a dissertation – as do the amazing Brenda Fischer, Bruce Fischer, Hanah VanderMeulen, Matt VanderMeulen, Erin Nowack, Elizabeth Sanders, Mike Sanders, Christy Crossman and Cory McDaniel, all of whom gave up their precious time more than once to play with Dean. My son, Dean Michael Fischer, has brought happiness and excitement to my life since the day he was born. It is impossible to be cranky or stressed around Dean’s energetic enthusiasm and I am more thankful than I can express for the light that is Dean. I wish for him the kind of viii love and support I have received so that when he’s a “grown up” he can pursue his dreams the way I have been able to. Finally, I would like to express how fortunate I am to have the love and support of Nate Fischer (a.k.a.
