My Robinson ancestor, Isaac Robinson, b abt 1793, may be from Lincoln Co, NC. While I cannot prove at this time that he is from Lincoln Co, my intuition tells me that he may be based on some weak evidence.
The 1850 census tells me that he is from NC and that he and his family are found in Sevier Co, TN in 1850. An unknown wife is the mother of his eldest daughter, Cecilia. His second wife, Nancy, is the mother of these children: Martha, Valentine, David, Alexander. Absalom, and John Wesley.
