Are you sure you are searching for the correct person? Do you know that the John Staunton on the ship George actually arrived in America? That was early enough that he should have received land within a few years, yet he's not in the records. The court records of Surry County from 1652 through 1682 are preserved and on-line at Ancestry. There is no James or John Stanton/Staunton, but there is a Robert frequently mentioned. It might be worth checking him out. I've worked with early Virginia records quite a bit and it seems these early settlers spent a lot of time in court for one reason or another. The only 'Stantons' mentioned in Virginia land records before 1666 are Christopher, Daniell, Henry, Mary, Richard, Robert, Thomas, and William.
