I am looking for definitive proof of the parents of my great great greatgrandfather, who would be my great great great greatgrandparents. John Robertson Duncan was born November 6,1803 in the Pendleton district of South Carolina. He married Sarah (sally) McCormick born July 3,1805 in wren county virginia. They lived and died in Hancock county, Indiana. I have all this information but do not know with certainty who the parents were. if anyone knows anything I would really appreciate hearing from you. Thanks in advance. Karmel
