No.I think that R.G. and John were brothers.They were both the sons of Henry.Again, the problem persists of keeping the names straight.I know that there were several with the name Henry.I think that a good clue is the 1850 TX Census.The men, and women born in AL were Jane (28), Lafayette (17), Louisa A. (26), M.G. (24), Marian (25), R.G. (36), Washington (17).Sophia was their mother.In this same census, she is listed as a 58 year old, born in NC.Henry is not listed, of course, because he had already passed away.
