DNA Match matches oral history[PEGUES]
I got a DNA match on 23andme that confirms my family's oral history told to me by my late uncle stating that the father of my maternal great-great grandmother was a white man from Mansfield, Louisiana named William Thomas Pegues! The DNA match told me that his maternal grandmother was the daughter of William Thomas Pegues older brother!
I guess DNA technology can be useful when you have enough information and knowledge.
