I recently have been doing research on the Hardin's myself. I am a John Wesley Hardin's was my great grandfather's cousin. . The Hardin family on my side is also has a mean streak. The Hardin families does have a Pre-disposition of mean streak and cruelty. It comes from out ancestors. The name Hardin actually descends from France. It used to be Hardineough. When the families migrated from France they dropped most of it and it was changed of the centuries.
