I am also trying to find out who the William Johnson is in this picture. Elizabeth is the step-daughter of William Johnson, so I am assuming Mariah was married to a Vest. I think the children listed are Elizabeth's children and I assume she was not married. They are in Forsyth County, NC in 1850. Mariah Johnson 36 Wiliam Johnson 35 Elizabeth Vest 11-step daughter Isham Vest9 John H Johnson4 Parmelia Johnson 1
IN East Bend, NC in 1870. Still in East Bend in 1880. I can find no record after 1880. If you have any new information, please let me know.
