I once read a magazine article which argued that George Washington, being a Southerner, spoke with a drawl, y'all. It should be noted that the magazine in question was The Southern Partisan.

There are some interesting videos on YouTube covering this subject.

From what I’ve seen, Washington sounded like a typical upper class British gentleman.

Washington grew up where the Tidewater/Piedmont Virginia accent was found. Still is in pockets. “You all” is common there rather then “y’all”.
