I might have incorrect records, but I show Mary Ann was the third child of Jonathan and Elizabeth Trexler. I show their first born as Malinda Jane b.17 Nov 1828 in NC. Their second child as Angenette (Nettie) b. 1831 in NC. Their third child as Mary Ann b. 1833 also in NC. Their tenth child, Thomas Jefferson Hulan was my G-G-Grandfather. Am I incorrect? Do you have better information?
