Daniel married Mary “Polly” Heavner on 23 Dec 1819 in Lewis County, West Virginia. They had thirteen children in the order of birth: Abraham Jefferson, Jemima, Jacob, Isaac, Anna, Stephen, Mary Jane, Sena, Nicholas, George Washington, Christena, Ellen Elizabeth, and Sarah.
Daniel Post was a residence on the US Census in 1830 and 1840. Barbour County was formed in 1850 and the family is in Warren District in Upshur County by 1870 and 1880. Death for Daniel came on 18 July 1880 at Rooting Creek in Upshur County, West Virginia. It’s possible that based on the changes of county boundaries, they lived in the same general area.
