When did the 'American' accent come about?

And a somewhat relevant question: What accent would someone like George Washington, Abraham Lincoln, and Mark Twain have spoke in?

Is it OK if I add a question along with this? Feel free to delete this comment if not.

How come the Australian accent didn't become more like the American one and vice versa given that they were once part of Britain's colonial empire?
