It's a pdf and about 140 pages. Some of the coonasses I know, knew.
About page 4? is a Martial Babin. Hell we rednecks always said Marshall.
Most of what I've read is true, so it'll save me a repeat telling.
But, it won't stop the BS.
BTW. Lots of older cajun men had girls names. There's a story about this, but I'm not hunting it.
