I am missing Nathan Viney's (of WV) older children. They were last known to be in 1840 in Daviess county, Missouri. They didn't come with the parents and 4 youngest children to Madison county Iowa. Here are they approx. ages.
2 male born 1825-1830 1 female 1825-1830 2 female 1835-1840
They were most likely born in Nicholas county VA (where family was in 1830) or in Monroe county where the parents were from.
