Individual Details

Francis appeared in the 1850, 1860, 1870, and 1880 censuses in Warren Co KY. In 1850, wife Martha C. and children John age 8, Nancy D. age 6, Robert age 4 and Mary A, age 2.
In 1860, wife Mary was present as were John, Nancy, Robert and Mary, children of Martha. Then were listed Eliza age 5, Luther age 3, Francis age 1. Then Clay Jackson age 20 and Martha age 22 - who were they? They weren't in the family 10 years earlier - were they stepchildren and should have been listed as Sears?

Probably the Francis W. Jackson who received license for a horse [stallion] or jack [mule] in Warren Co in 1852-1855

1870, Francis W. Jackson's wife is now Nancy. A Drucilla Jackson age 27 is living there - in 1850 the child Nancy was listed as Nancy D. - she would be about this age, has she adopted her middle name to avoid confusion? Robert, Mary, Luther and Frank are all there. The oldest child John gone from home or deceased. Also missing is Eliza who be age 15 - she could be married or, more likely, she has died.

In 1880, Nancy is still with Frank. Robert S. is now 33, but still living at home. So is Mary, Luther, and Frank W. Drucilla is still there but she is now Drucilla O'Neal, age 37, with her children Franklin [age 6] & John [age 4] O'Neal.
