A good person to talk to regarding repatriation is Perry Ground at Sainte Marie Among the Iroquois. Perry is a Native American, and has a gift for discussing this issue without making people feel defensive. He has lectured for students at the Cooperstown Graduate Program and also spoke on the subjects of repatriation and interpreting existing cultures at the annual meeting of the Association for Living Historical Farms and Agricultural Museums. I believe one of his co-workers is a member of Museum-L. Are you out there Kim? If memory serves the museum is in Liverpool, NY.
