Seriously, and with no offense to the LDS Freepers, I put my trust in the historians and ethnographers who agree that Linguistically, they are part of the Iroquoian-language family and are thought to have migrated south in ancient times from the Great Lakes region, where other Iroquoian-speaking peoples were located.

Language is not a reliable marker of ethnic origin, since a new language is easily learned, and an old language forgotten within two or three generations. Think of all the American immigrant families and their grandchildren and great-grandchildren, who couldn't speak more than a word or two of the “old” language if a gun was held to their heads, having learned only English.

So language is NOT a good indicator of heredity.
