Portrait of John Ross
From Tennessee history:
Although only one-eighth Cherokee by blood and bearing no physical features common to Native Americans, John Ross considered himself a full-blood Cherokee... . ...known among them as Tsan-usdi – a Cherokee term meaning "Little John". As he grew into manhood he was called Guwi–sguwi meaning "the egret or swan" – a name that came to be known over the years as "Coowescoowe".
