Perchance the Cimarron?

Brig. Gen. Albert Pike, Confederate States America, for a short time before The War Between the States, was an Indian Commissioner for the Confederacy. In the late 1850's, his law practice represented the Cherokees. He led a brigade of Cherokee Indians at the Battle of Pea Ridge (Elkhorn Tavern), 1862.

It seems he had no contact with the Cherokees after the War.
He edited the "Memphis Appeal," and then moved to Washington, D. C., where he practiced law. He was a Scottish Rite Mason and wrote extensively on Masonic ritual.

He also was a poet, and wrote "Ode to a Mocking Bird" among many others. He was supposed to be fluent in seventeen languages but this cannot be verified.
