My husbands great great grandfather was Moses T. Whitehead b. 1825 SC. Married Margaret S. Bryant b. 1829 NC. Their children were Sarah(Sallie), James Bradford, Henry Stephen, John Bennett, Thomas Austin, Worford Franklyn, Andrew Johnson, George Jefferson, Thomas Bryant, Joseph Young and William Jackson.
I don't have a lot of info but am willing to share what I do have. I can send you a family group sheet abd put you in touch with another lady that can give you more extensive info on your line. Most of them lived and died in Texas around the Williamson County area.
Hope this has helped you. If you need anything else please feel free to email me.
