This report describes the activities and findings of the Trail of Tears Association’s Oklahoma Chapter research team, which in August 2009 made a week-long trip to the National Archives for its fourth consecutive year. This report, similar to Research Report No. 1 (see above), briefly explains the nature and major accomplishments from the trip. This report also lists the various record groups, entry numbers, and box numbers that the team investigated. As the team notes, some boxes revealed more information than others, and many boxes contained information about tribes other than the Cherokee. The 2009 research investigated records in these groups: RG 75 (Bureau of Indian Affairs), RG 92 (Office of the Quartermaster General), RG 94 (Records of the Adjutant General’s Office), 192 (Office of the Commissary General of Subsistence), and RG 393 (Register of Correspondence with General Winfield Scott, part of Records of U.S. Army Continental Commands, 1821-1920) as well as RG 217.
