Nancy, Southern Pioneers has a specific scope; you should check its project page. For example, I would not put people who stayed in Virginia into Southern Pioneers-- I believe Southern Pioneers is for people who "pioneered" OUT of the original colonies. But again, check the project page for specifics.
Virginia and Maryland and North/South Carolinas cover pre- and post- revolutionary war.
I hope we'll have something for you all soon about what's to become of US Southern Colonies.
