VA was first here in 1607. MD was founded by Lord Baltimore as a safe place for Catholics to worship. As VA expanded, farmers from the back country settled in NC and the English nobility tended to settle in SC. James Oglethorpe thought that land between SC and Spanish Florida would make a good place for debtors and the poor to make a fresh start. So he settled the land and successfully defended it against Spanish attacks.
