I saw your posting on the Lawrence Co, Ohio message board. I am not connected to this family but just trying to help.
This appears to me to be your Nancy Ellen Aldridge with her parents:
1860 Aid Twp, Lawrence Co, Ohio Mount C. Aldridge, 37, born Ky Minerva, 28, born Ohio Nancy E., 10, Ohio Lucina, 5, Ohio Allistair, 1, Ohio
Nancy Ellen Aldridge and John Null's marriage record says she was born about 1849 so her age in the 1860 census fits.
1850 Aid Twp, Lawrence Co, Ohio, Oct 15, 1850 M.C. Auldridge, 24, farmer, born Va Minerva Auldridge, 19, Ohio (I guess they couldn't make up their minds where Mount C. Aldridge was born)
Nancy was married in 1867 so she is not in her parents home in 1870:
1870 Aid Twp, Lawrence Co, Ohio Mount C. Aldridge, 47, farmer, Ohio Minerva, 38, Ohio Lucinda, 15, Ohio Allace A., 13, Ohio Mount C., 8, Ohio Mary J., 5, Ohio Marcus D., 1, Ohio Nancy Green, 70, Tennessee
