I have no idea where this family is. Joshua W Tharp was born ca 1848, he says in 1848,in Greenbrier County. He married Mary E McMillion, 16 May 1870. >From that marriage certificate he says his parents were: Daniel T Tharp and Mary E., no last name given. I cannot find either one on 1850-60 or 1870 Greenbrier Census, can someone help?
