I wonder if your Joseph could be another son of Benjamin Mize of Rowan Co., NC, later of Patrick Co., VA, later of Barron Co., KY. A large group of the family moved via Tennessee, to Kentucky, then to Illinois and Iowa. His son, James Mize named one of his sons Thompson Mize. The names are so familar and they were following the same migration pattern that it seems possible he is another son.
