With participation this could be a locus for discussion of topics relating to Native American culture and linguistic history. Topics could include the classification of Native American languages both living and extinct, Trail of Tears, Ghost Dance, skinwalkers, or other topics that come to mind. I'm not aware of all the details of how these languages are classified, but I know that the Algonquin family is one of the major branches. Is the Mohawk language part of the Algonquin family? I'm not sure. Maybe Mohawk is Athabascan. I'm fairly sure that Cherokee is not in the Algonquin family. Apache may be part of the Uto-Aztec family. Speak up if you know the answer to this. I'm interested in the Croatan tribe and Melungeon people. I think that they are somehow related through intermarriage. Could the Melungeons be of Turkish origin? Some of them think they are. What say you?
As noted elsethread, North American native languages aren't entirely extinct.
Ethnologue lists the Iriquoian languages, including Mohawk and Cherokee, as a small independent family.
The various Apache languages are generally understood to be in the Athapaskan branch of Na-Dene (or, I suppose, Dene-Yeneseian, if that connection is accepted.)
