==Cherokee== 
 Seeing the mention of a Cherokee ancestry for Johnny Depp, I am reminded that, for some reason, while other Indian tribes became extinct or mixed but separated, the Cherokee mixed a lot with White colonizers and, as a result, a sizeable part of Americans have some Cherokee ancestry (I am also reminded of Tina Turner). 
 I guess that most of the North American mestizos come from Cherokees (the rest of the White/Black mixes with Indians are probably classed as some kind of Indian). 
 There is also a phenomenon of (modern) Americans claiming a (false) Cherokee ancestry because it is in vogue. 
 Somebody more knowledgeable could extend over it.
