Wm Jefferson GRisham's father John

have hit several walls, Wm Jefferson was committed to Whitfield Insane Asylum and died & is buried there. cause of death is epilepsy. on the death cert, it lists no mother, father John. Have plans to contact Asylum and start process to view or even copy medical records, which i hope will hold the key to open the door. Wm Jefferson seems to have been blackballed by the family and I find myself defending him. Does anyone have any leads to share? Bonnie Grisham
