Not taking sides in the Cherokee Freedmen controversy because I don’t know enough about it … still, see the two pages-images from the Tribe’s advertising at this Wikipedia article!
Or even the front page of the American Indian College Fund site: The masthead image at top including a student, rotates among four different folks, one an Irish-looking young lady (except her eyes). Red hair and turquoise, best of both worlds!
Or this 2005 NY Times Magazine piece about Mixed-Bloods / urbanized Natives, and others, “going Native.” I believe the author is mistaken or underinformed about some things, but maybe I’ve been studying it more than he has(!). (NB: The new Circe Sturm book mentioned there doesn’t seem to be out yet: it looks like her research continued longer than expected. [Apparently post-grad research can go on and on!] I get more potentially helpful hits searching not via the then-working title “Claiming Redness,” but the subtitle “Racial and Cultural Politics of Becoming Cherokee.”)
(The Times piece reminds me of how some Mixed-Blood activists / theorists insist on our right to identify as time, place, company, life-stage, etc., sall for. But U.S.-rotted Mixed-Bloods mostly didn’t develope as solid a Metis / Mestizo / Mestico / Mulatto identity as Canada or Latin America have — painful as it may have been going through it for them, constantly ‘between tribes,’ Native and European / African. We should be grateful to them for it.)
