Dear Ms. Malone,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series National Register of Historic Places and National Historic Landmarks Program Records, 2013 - 2017 in the Records of the National Park Service (Record Group 79) that includes an item titled Georgia SP Ossabaw Island. It describes some of the history of the relationship between the Yamacraw band and the British settlers in what is now Georgia. This item has been digitized and is available for review through the Catalog.
We also located the series State Project Reports and Research Publications, 1933 - 1943 in the Records of the Work Projects Administration (Record Group 69) that includes the file units E 78.G61 Irene Mound Site, Chatham County, Georgia 1941 and E 78.G62 Works Progress Administration Excavations at Irene Mound (Georgia) 1938. These may contain records about the excavations conducted near the band’s New Yamacraw settlement by the Works Progress Administration. These file units have not been digitized. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) at email@example.com.

We apologize for this inconvenience and appreciate your understanding and patience as we balance mission-critical work and the safety of our staff during the pandemic.

In addition, you may wish to contact the Georgia Historical Society, particularly regarding their Joseph Vallence Bevan Papers and Coastal Georgia Archaeology Society collection on the Irene Mound collections that may include further information pertaining to the Yamacraw band. Their website also includes an article regarding the relationship between Tomochichi, the leader of the Yamacraw, and James Oglethorpe, leader of the British settlers in the region.
We hope this is helpful. Best of luck with your research!
