I am trying to get information on my grandfather's family as he had always stated we have Blackfoot indian. I have been told it's from his mothers side, Margaret A. Johnson/Johnston (married Carl C. DeHaven). Her father is Ferdinand J. Johnston and it appears mother is Emma Herrell. Emma is supposedly the American Indian. Ferdinand and Emma's children appear to be Margaret, Anne or Annie, Mary V. (went by Viola), Robert, Frank and Bertha. Any one who can help me trace Ferdinand's wife Emma or help me find the correct info I would greatly appreciate it. Ferdinand was a farmer in Berkeley Springs West Virginia.
