Based on John Hayzlett's will in Kanawha Co, VA/WV in 1830 and land sales after his death, we have been able to reconstruct the names of his children along with several sons in law.
The children of John and Anna (Becks?) Hayzlett (most birthdates based on census records): Andrew H. (1802-1886)m. Elizabeth Hughart1827 Sarah(ca 1805)m. James Billups James B. (b. 1806-1855)m. 1. Jane Snodgrass 2. Angelina Beach Washington Thomas (1809-1888)m. Rebecca Bryant 1832 William (b.1813-1887)m.1. Annie Sample 2. Elizabeth Williams Julia Ann(b.ca 1814/15 )m. John Moore 1836 Dicey (b. 1821/22m. Wiley King Rebeccam. William Barnett
All but Sarah, Washington, and Dicey appear to have moved to Hancock Co, IN and spread out from there.
I'd love to hear from descendants of these children.
