Land Grants in Darlington placed most of them in Darlington District and most found on the 1790 census through 1820 before the great migration into Georgia and Alabama began.
Peter and John were the two sons that we know of because of the book "Sketches" but it is quite possible that Jesse, Paul, Ralph and Phillip were related.
Mordecai had a younger son named James and quite possibly the elder James Edward Bozeman was the brother of Mordecai, and possibly John Lewis Bozeman was another brother.
