General Ely S. Parker:

Born into New York's Seneca tribe in 1828, Ely S. Parker became a sachem of the Seneca's wolf clan in 1852. He enlisted in the Union forces during the Civil War, eventually serving as General Ulysses S. Grant's adjutant and rising to the rank of brevet brigadier general. Following Grant's election to the presidency, Parker was appointed the commissioner of Indian Affairs in 1869, the first Native American to hold this post.
