Not these ones, as far as I know, but there are other frauds in Scotland and Ireland now claiming to be "Native Scottish", or "native" to Scotland or Ireland because they are English or American people who moved there in order to exploit the culture. They were trying to do the "Indigenous Scottish", "Indigenous Irish" or "Indigenous European" claim, as is also claimed by organized white supremacists. Somehow now they think falsely claiming to be Native (or "native") is better?
Liars, colonists and exploiters. Self-indigenization by colonists, any way you spell it.
