Rene La Force II, mentioned in his father's will, was born at Virginia. I've recently stumbled across an old book that explains he was an outspoken Tory therefore his neighbors ran him off.
They make it seem like the whole family headed to KY. After crossing into KY they made camp one night. Two sons went off to hunt for dinner & caught something. One son laid down his gun to help clean their kill. After going to bed he remembered his loaded gun sitting outside. While trying to retrieve it in the dark it went off killing his father. Rene II was buried near their camp somewhere in KY.
