A number of talented students have contributed to the collection and analysis of the data. Heading this list are Jeffery Graham and Janine L. F. Wilson who have served as the project's lead research assistants. Amir Amadi, Raphael Avraham, Audrey Goodwater, Rowena Gray, Pablo Jenkins, Teresa Nguyen, and Joanna Parks at UC Davis; Edward Esau of UC Riverside and the Historic Natchez Foundation; Tiffany Hamelin, University of Mississippi; Peter Malaspina, University of North Carolina; Jeremy Meiners, Washington University; Kristi Barnes, Auburn University; and Eric Sumral, Millsaps College, have all spent countless hours poring over plantation records. We give special thanks to Shelagh Mackay, whose attention to detail and insights have left a positive mark on our research. Librarians across the South have been of great assistance in identifying sources.
