Homer - There were nine children. After Roxan Miles Gross died, William Dunbar married Margaret Moore Simmons, dau. of John and Isbella Findley Moore and widow of Benjamin Franklin Simmons. She had two children:John Franklin Simmons (m. Nancy Missouri Gross) and Annetta Subelle Simmons (m. William Jonathan Gross). They had no children together; I guess they thought eleven were enough. William Jonathan and Belle Gross were stepbrother and sister and my great-grandparents. My mother was raised in Carthage with lots of Gross cousins. Now, for Felix and Hans. Do you have documentation that Jonathan Gross was Felix's son? The genealogist on our side of the family that supported this theory was never able to prove it to anyone else. Since you come at this from another line, you might be able to help us.
