Got a request about him. He's an artist and silversmith, site is davidfourfeathers.com
This is somewhat different from the usual people we report on. McQuaine is not accused of being a ceremony seller or passing himself off as a healer.
He is using a claim of being NDN to sell his art. But looking at the wording on his site, he is careful to not say he is enrolled or that his works are Cherokee/Creek. Instead he makes it clear he learned from a Navajo, but never calls it Navajo jewelry. This is a gray area, and technically not illegal, but deceptive.
McQuain says his family is from OK, Cherokee/Creek, but does not say which ancestor(s). He says elsewhere he is 1/4. He's not enrolled I think, or no doubt would be using that fact to sell his jewelry as NDN made.
