I don't think we really have a thread that this fits into perfectly, but since it's a regional dialect thing I thought that this one would do.
When I was in grade school, there was a girl in my class that used the phrase "has done did", as in "June has done did her homework". At the time, being a judgmental little kid, I just took this as proof that the girl in question was dumb. As an adult, I realize that she'd just internalized the grammar of the English spoken in her home, the same as I had, and that I'd just gotten lucky in terms of having parents who spoke Standard English.
Is that little snippet of grammar enough to identify what her dialect was? If it helps, this was in rural NE Kansas, and I know that her parents (and probably her grandparents) grew up within about 5 miles of where she did.
