I have just found out that my Camfields came from South Dakota. My great-grandfather, Oscar Earl Camfield, was possibly born there (c. 1885). He had an uncle named W.W. "Cappy" and an aunt Mary (possibly Mary Elizabeth). Cappy and Oscar went to Muhlenberg Co. KY sometime before 1913. Mary, the aunt, married a Camfield too - George. Possibly cousins? Please reply if you have any Camfields in South Dakota during this period.
