Dialect question: I've heard the term "Naughts (or maybe Noughts) and Crosses" but not "Aughts and Crosses." Do naught and aught mean exactly the same thing? Is it a regional dialect thing? Where does it come from?

My dad, who grew up on a farm in Kentucky, used the word "aught" (or it might have been "naught"—it's hard to tell the difference between "a naught" and "an aught") where people today would normally say "zero." I've often wondered whether his dialect could be traced to a certain region of England. Any dialect experts out there? If I described his dialect in detail, could you identify it? Calling 'Enry 'Iggins!

There's lots of other stuff I could list, like using "chimley" for "chimney" and so on.

I assume my ancestry is mostly English, because nearly all my known ancestors had English-sounding names, but no one has ever actually traced them back that far.

Please excuse the thread creep.
