Bernice, Henry Francis Stillwell is s/o of a different Jacob Stillwell (ca 1785, VA - ca 1834, Burke Co, NC) and Mary [last name unknown] (ca 1788, NC - 1862, Burke Co, NC). If you are able, check the following Burke Co, NC - Rec of Inv of Sales of Estates (1832-1838) p. 16 - Jacob Stillwell - sale Aug 19, 1834, Court Oct 28, 1834. Admin: Peter Stillwell, Purchasers: Betsy, Hannah, John, Mary, Middleton S.
Jacob is s/o John Stillwell (bef 1740, probably NJ - ca 1814, Burke Co, NC) and Maude (no info on her). John is a brick wall for me. I can help you with with some of his descendants if you need the info.
I have also given info to Scott Stillwell who descends from Henry Francis Stillwell.
