The two sons are John B. Bobbitt born in 1830 and William C. Bobbitt born in 1840. The three eldest daughters belong to the first family and probably are Sarah, Delitha, and Matilda. The oldest female is of course Elizabeth S. (Oliphant) Bobbitt.
In the 1850 census, the family was counted as family # 296.

Edward S. Bobbitt was a brother of John B. Bobbitt and he was the last child of William and Elizabeth Bobbitt. He apparently was visiting when the census was taken.
From these records it is easy to determine which of the children' married and remained in Tennessee and which ones married and lived in Mississippi.
The war between the states of course caused many of the children to migrate to other sections of the country.
