I hear you Davidpope, cultural frustration is tough, but those of Native and Scottish heritage have practiced elaborate embroder, beadwork and feather wearing on the Glengarry since the early 1700's I would like to partake in that historical cultural blend as it is a great door to talk about the historical impact of early Scotsman in the United States. However I just want to make sure i am doing so without infringing on the rights of chiefs etc. To which as discussed I think that any feather that is not an eagle feather would be appropriate if hung off the back of the Glengary. would be the solution.

Macrob,
Eastern band Cherokee is extremely strict. Oklahoma only goes off the Dawes rolls, there are actually 15 Federal Cherokee Census rolls. My ancestors are on the Miller roll (The census before the Baker roll was taken) The Hester Roll, The Henderson roll. Therefore we can not get Federal Recognition only State recognition. The State recognized tribes won our rights to have eagle feathers in 2013. Although we can not use the repository they can not be confiscated and we can not legally be fined to possession according to the 5th district Federal Court ruling.
Your family may not be able to enroll federally but if you can prove your lineage with birth, death and marriage records to a family member on the other federal rolls you could possibly get state recognition for your family. Although Cherokee Nation isn't a fan of it, it would protect your religious rights. Sadly the only culture/religion regulated by the Government....
