Could someone tell me how to find a list of the old Saw Mills in Lawerence Co and Independence Counties?The myth i've been told about my Ggrandfather was that he was killed in a Saw Mill accident,he was on a 1930 Census in Lawerence county so it would have been sometime after that,,supposedly he was killed when a log crushed his chest,, Thanks Also,,Whether or not there would be records kept in the Saw Mills?
