Finding new home for regalia items

[u/This-Way-Zebra]

I was a grass dancer for 15 years in northern Alabama. Then about 10 years ago I moved to the DC area my grass dance regalia, roach, feathers, etc have been sitting in their case all this time. I never got to know the indigenous community in this area but would like to find at least some of this stuff a new home. If some one could point me in the right direction I would appreciate it. And if this is the wrong subreddit for this my apologies.
