Odd how 'gwine' is attributed only to African-Americans. It was also once common among unlettered Whites in Maryland and elsewhere in the southeast. Please peruse the journals of folklore and language at the nearest decent library.

Folklorists collect and record their material in the form in which they find it; much of our history and its meaning would be lost if the songs and stories of the past had been been transliterated and strait-jacketed to suit narrow-minded squeamish censors.
