There is quite a history of the Scots & the First Nations, Riverkilt...from the Metis in Canada, to the Orkneymen who worked for the Hudson's Bay Company and the Scots fur traders of the North West Company, Scots have always indentified with the Nations.

Check out this chapter from the book "Scots in the North American West":

Another good book is "Scottish Highlanders, Indian Peoples", by James Hunter, about the MacDonald family and their relationship with the Nez Perce Tribe in Montana.
