Tracy, my great great aunt Elizabeth was the second child and daughter born circa 1837 in the Old Barnwell District, near Bamberg, SC, to William McCormick and Elizabeth Varn Rentz McCormick. She had six other siblings and two half siblings as I know now. The whole were Sarah, George, Julie Anna, Lavinia, John A., and Lazarus. The half brother was George Rentz and the sister was Elizabeth Olive Rentz. Two of her nephews might have lived in Murfreesboro, NC. If you think this might be the right family, we can talk further.
