Individual Details

I find no spouse suggested for Henry Terry. Since the name Barton seems to first appear as a son of Henry, it's quite possible his wife's surname was Barton.
Henry possibly died in Pittsylvania Co VA - if so this would certainly add credence to his suggested relationship as Barton Sr's father.
