How many major Virginia American Indian languages were spoken?

Answer 1

The tidewater area of coastal Virginia was occupied by around 30 small tribes known collectively as the Powhatan, speaking a language known today as "Virginia Algonquian" - but it is likely that many different dialects were originally spoken, Since the language became extinct by the 1790s we have very little evidence to form a sound conclusion.

Other Algonquian-speaking people were bands of the Shawnee.

Surprisingly, many other native tribes in Virginia spoke languages of the Siouan family, among them the Manahoac, Monacan, Nahyassan, Occaneechi, Saponi and Tutelo.

Tribes speaking Iroquoian languages were the Meherrin and Nottaway.

So there were three language families represented in Virginia: Algonquian, Siouan and Iroquoian.
