For ten points, name this author of Systems of Consanguinity and Affinity and Ancient Society.
A product of Aurora Academy, he married Mary Elizabeth Steele after beginning to practice law. He draws parallels between humans and beavers, both of whom he suggests have a "moral sense" and "free intellect" in The American Beaver and his Works. His interviews with such men as Jemmy Johnson were facilitated by a family that included Caroline, Levi, Newton, William, Elizabeth and, most famously, Ely S. Parker; these interviews resulted in the book League of the Ho-de-no-sau-nee. Endowed with a Seneca name meaning "bridging the gap," his major work posits evolution of society from savagery, to barbarism, to civilization.
