I finally located my GGGrandfather, John M. McKINNEY (the M. could be Mathew). In the 1850 Henry Co. AL census, his birth place is SC, his is listed with wife Emily (she was born in AL, and 20 years younger than John), he has a daughter Sarah E. (Sarah was also born in SC.) He is a blacksmith. John was married before, but her name is not known, The first marriage he had 2 daughters (I did not know their names before this census) and one son, Frank. Frank moved into Texas as a young man. Can anyone tell me how or where to start a search in SC, for him, as I don't know what county he was in. Any help would be greatly appreciated! Thanks in advance, please email me direct.
