Because of my accent, or lack thereof, and where I live (DFW), people have always asked me where I was raised. When I ask why, it’s because they think I’m from Ohio. Incidentally, I was born and raised in Arlington, Texas. I have honestly never been to Ohio. However, my paternal grandfather was born and raised in Pennsylvania. He and his heritage is the only Northern, or Yankee, heritage I have. Everyone else, for at least 7 generations is American and from the South.
Maybe I’m rare, but on all sides of my tree, including my paternal grandfather’s line, the immigrant ancestor came to America before The Revolution (and in some cases, long beforehand).
I got the impression that the DFW part of Texas was essentially the midwest.
