James Alva Lee of MS and TX

I'm researching James Alva Lee born 1846 in MS. I believe his father was Thomas Lee born about 1820 in SC, married Jemah or Jeemah Byrd, daughter of Elam Byrd. James' family moved to Texas and lived in the Liberty County/Cleveland Texas area. My grandmother was Harriet Evans (Hattie) Lee, James' daughter.
