Jesse and Isabella's children, according to my humble reconstruction, were as follows: A.B.(perhaps Alexander) b.1808 SC (married Sarah); Anna b.1810-12 SC (married Jeremiah Freeland); Isabella b.1814 SC (married William Sims);Zelphia b.1815? SC (married Howell Eldridge Freeland);Mary Ann b.1815 SC (married 1. Dudley Taylor 2. Benjamin Dugger);Adeline Rachel b.1825 SC (married George Taylor);Cyntha b. ~1825 SC/GA (married Albert Stiles)Jesse F. b.1828 GA;John M.V. (McV?) b.1831 GA;Rosetta b.1832 GA (married Charles/John Stiles);Javan b.1834 GA. Dates of birth are rough approximations due to discrepancies on census reports. There is no concrete documentation showing A.B., Mary Ann, Adeline, and Cyntha as children of Jesse and Isabella. The 1826 marriage record between an *Abby* Black and Jesse Campbell does not yet convince me that Isabella and Abby are one and the same. The 1826 would indicate a "late" marriage considering A.B. and possibly six other children were born prior to 1826,starting as early as 1808. A January 6, 1826 will of Mary Black mentioned her daughter "Abby wife of Jesse Campbell of Georgia."The only Jesse Campbell listed on the 1820 GA census was in Liberty Co. He was probably married and had one male child (10-16). If the 1826 marriage for Abby and Jesse Campbell is for Mary Black's daughter, the marriage must have taken place prior in the first five days of January. More than half of these Campbell children were born in SC. Jesse showed up in Habersham Co on the 1830 census (Jesse Cammel). Both a Jesse Campbell and an Alexander Campbell participated in the land lottery of 1832.
In other words, it isn't easy to root out Jesse and Isabella using the available documents. I would rather have holes in the genealogy than make something fit without sound documentation or convincing circumstantial evidence. Perhaps our common search will produce results. Please feel free to "fire away" at any of my conjectures.
