The remains of a Winnebago man are being turned over to his tribe for burial after decades in a museum.

The Lincoln Journal Star reports  that the man had been among Native Americans who were forced out of Minnesota and into South Dakota after the Sioux uprising in 1862. His remains were found by a U.S. Army surgeon about five miles south of Fort Randall along a riverbank in south-central South Dakota.

The remains eventually wound up at the Smithsonian Institution’s National Museum of Natural History. The museum is following a 1989 federal law in turning over the remains to the tribe.

The tribe has set aside space for remains at the Winnebago village cemetery on the tribe’s Winnebago reservation in northeast Nebraska.
