I have always heard that William Davis Dunnam had died around 1857, in Union Co. Miss.I found this record in the 1860 census for Itawamba Co. Miss. 934William Dunham52Ga Elizabeth 54Ga Adalyne20Ala Susan18Ala Martha17Ala James13Miss. William11Miss. Harriett8Miss. Theopholus 6Miss.
The reason I feel confident that this is the same family is because Theopholus is my gr-gr-grandfather, and his age is correct.
