Was Joan of Arc a peasant?

In a sense, as Domremy was what we would now call a Hick town, but by rural standards she and family were relatively well-off. I mean, you would not call the Virginian (landed Gentry) Sod-busters or plowmen, right. as she was in effect raised to the nobility- she was the Baronne Jeanne d'Arc of Rheims- de facto after the battle for that French town. one wonders out loud- why did Charles VII seemingly betray Joan after she had practically won the throne for him- he didn't pull strings to get her out of captivity- emergency edicts- Royal Pardons- I realize they did not have walkie talkies ( or did they, Jeanne) in those days, but even still, Kings go Forth- or should.
