I was just reading your post! LOL! I'm not sure from where she comes, but she has that haughty, uppity, air about her that drives me nuts.
She has, to me anyway, that backwoods twang with a harsh delivery that a lot of women here in Oklahoma have. The ones who were "fetched up" have a much softer delivery. She sounds almost East Texas (no offense Texans.) The Piney Woods type of an accent.
