I am doing family research on William Marshall and his children. William Marshall and several of his children (George, John, Elisha, Jordan, David, James, Catherine, and Diana and later Mary Marshall Carpenter who was the wife of Abner Carpenter) as well some Carpenter family members came to Illinois from Jackson Co., TN around 1830. They first settled in the Cass Co., Mason Co., and Sangamon Valley area and they spread out to Adams Co. and Brown Co. in IL and DeKalb Co., Missouri. If you know any info on these families or are descended from any of them please contact me so we can exchange information and we can compare notes. James Marshall was my gg grandfather.
