According to my sources, Elizabeth Margaret Black, daughter of Samuel and Catherine Shaw Black, married Samuel Price, Sr. in 1773 and lived in Greenbrier Co., Va (now West Virginia). Margaret died between 1792 and 1797. Samuel Price then married again. Children of Samuel Price and Margaret Black were Sarah "Sally" Price, Mary, Samuel Jr., Jacob. The second wife of Samuel Black was also named Margaret and she was daughter of Samuel and Jane Black of Augusta Co., Va.
