Thomas Jefferson Brigman - Need work on this profile and tree

I've been looking into some Brigman connections and found this mess. Thomas Jefferson Brigman and a father (and likely mother for I have a will that I am going to attach to Isaac Brigman that lists his children and wife Fereby.

Most people did not have a middle name who were born in 1730, much less someone being named in honor of the nation's third president who wasn't born until 1743. So.......

Any thoughts. The Brigman tress is as messed up on Family Search as it is here. So don't depend on it for any verification. Maybe some sources, but I found Isaac's will on the SC Archives. Lists wife Fereby and sons John, Isaac, Lewis, Malachiah (sp), Moses, Thomas, Solomon, and daughters Sary and Mary.
