My g-g-grandfather, Joshua McDonald (sometimes erroneously listed as McDaniel) married Sally Wolf in Osage County in 1842. Her parents were Valentine Wolf, 1794 TN-1866 Gasconade, MO, and Mary J. Thompson, 1797 TN-1882 VA. I think Sally must have died in childbirth in 1846. Is this your family? I would love to find out more information.
