In which region of Virginia was the siouan language mainly spoken?

The Siouan language family was spoken by various tribes in the eastern and southern regions of Virginia, particularly:

* The Piedmont region: This area included tribes like the Manahoac, Occaneechi, and Saponi.

* The Coastal Plain region: This area included tribes like the Tuscarora, who later migrated to North Carolina.

It's important to remember that Virginia's history includes a complex mix of indigenous cultures, and language boundaries were not always rigid. Some tribes in these regions spoke languages from different families, and there were instances of language mixing and borrowing.
