Whether the Tunica-Biloxi Tribe sufficiently proved that it descended from the Tunica people associated with the Trudeau Plantation burial ground.
Holding
Yes. The evidence adequately established that the Tribe was the successor to the historical Tunica people and included descendants of the people who lived at Trudeau Plantation.
Reasoning
The court relied substantially on the federal government's final determination recognizing the contemporary Tunica-Biloxi Tribe. That determination found the Tribe to be the successor of the historical Tunica, Ofo, Avoyel, and part of the Biloxi tribes.
The Tribe did not need to produce a perfect genealogical chain linking every modern member to every person buried at Trudeau Plantation. The evidence showed that at least part of the historical Tunica tribe lived at Trudeau between 1731 and 1764, and no meaningful contrary evidence disputed that connection.
Evidence that the Tunicas had intermixed with other tribes did not defeat their status as descendants or successors of the historical Tunica community. Intermixing could not erase the Tribe's demonstrated historical relationship to the burial site and its goods.
