Scientology - Is Elrond Hubbard a Brother of the Blackfoot Tribe?

The Church of Scientology still continues this line to this day that Elrond Hubbard was a brother of the Blackfoot tribe. The Los Angeles Times reported on this in 1990. A historian named Hugh Dempsey said, blood brothers aren't even a thing the tribe has. It's like a Hollywood idea that was invented for Western movies. And it's amazing how little fact-checking people do if you claims a lie from far back enough like that.
