Did the william J Mitchell you are talking about have a son named Drury? My gggreat grandfather was Drury Mitchell born between 1755 and 1770, His 1st wife was sarah patsy taylor, We do not know what became of her or if she had any children.
He married his 2nd wife in Green County Ga. in 1800. Her name was Rhoda Lassiter.
We also believe Drurys father or grandfather might have been William James Mitchell.
