I am also looking for information on Robert Nidiffer, born 1829. He would be my gg-grandfather. Married Elizabeth Emaline Estep. His daughter, Malissa/Melissa is my great grandmother. I am looking for Native American lines. My aunts, who still live in Carter County, have pictures of the Nidiffer family, and there are strong native american characteristics. Can anyone give me info on Robert's parents? Please e-mail me with any info you may have.
