I have a photo of Waldo McIntosh who was simultaneously hereditary chief of the Creek Nation tribe and President of Clan McIntosh in the US. His great-grandfather was chief William McIntosh, who came over from Scotland and married a Creek Nation princess.

Anway, the picture is great- this old guy wearing a full feather headdress, red & black McIntosh tartan kilt, horsehair sporran and a beadwork kilt belt, with a white dress shirt and black necktie.
I'll scan it one of these days.
