Sorry for the delay. This is one of those project that I take on when time permits. I am Richard Carlton son, I believe that you are a cousin. I believe there are several of the Chastains and Griffiths in Dallas. I live in Fort Worth.
As far as I can tell You are at the same place I am. Unless I get a trip back east I am not sure what else I will dig up online. Right now I am trying to determine when John Cabe Carlton Settled in Texas? And trying to locate birth certificates, wedding license/certificates for Carter Braxton Carlton. If you have any of that or know some one who does let me know.
