The Jackson Whites ("Jacks and Whites") are NJ-area Lenape tribes which have administratively banded together, and they deny interest in building a casino. Like most people in the US who claim "Native American" heritage, they have a liberal and apparently quite varied mixture of European, African, and tribal origin.
I see they sought legal recognition around 1980 and came together administratively after that. My father was very interested in history and told me about them in the early 1950s. He is one reason I am really interested in GGG and Catastrophism.
