Oh, that elusive Simon Ashbrook Houston! The response to my query has been great, and most appreciated. Here's the frustrating thing: Beers, p 837, says that Isaac and Nancy (Ashbrook) Houston had 10 children. I know of nine, and their birthdates neatly accommodate Simon's 1822 birthdate: 1. John W., b 1818, d bef 1870, m Lucinda Cox 2. James, b 11 Nov 1825, d 1905, m Martha Jane Ramsey 3. Mary A., b 1828 4. Elizabeth, b 1830 5. Isaac, b 1833, m Christianna ___ 6. Nancy J., b 1835 7. William, b 1837 8. Abraham M., b Mar 1840, d 1 May 1926, m 1861 Margaretta Mounts 9.
