Diann, no, the book has no info from Francis Marion down. It only shows a comment from another researcher of Mark having a son Francis among a list of children. However, it does have information all the way back to the emigrant on Mark, his father Odean, his father John (killed by the Tories), his father John, son of the emigrant Heinrich Kesselberg. Some of that lineage lacks specific documentation, but I believe it is the best source of clues and information you are going to find. Dr. Castleberry can be written to at email@example.com
. In the interest of full disclosure, I assisted in compiling that information into family groupings, and do not claim infallibility. Any further primary data to assist in verification is always greatly welcomed.
I have two CASSELBERRY connections to the family, coming from the ones who stayed in Pennsylvania. All the CASTLEBERRY families in the early South came from their brother William, with his seven sons, who migrated out early, and his nephew John, son of John, another brother, who unfortunately is the less well proven of them.
