On the 1880 Tuscaloosa Co., Ala census, Thomas W. (age 53) and Mary (age 51) are listed with the following children: Lucandy - age 22 Mary - age 20 Thomas L. - age 18 Sarah - age 11 John - age 8 Elizabeth - age 5
Also on the 1880 Tuscaloosa Co., Ala census is the family of Dennis D. George (age 46)and his second wife Julia (age 38): Martha - age 17 Rebecca - age 14 William - age 12 Mary - age 12 John - age 8 Al - age 6.
Dennis married his second wife Julia Ann Wright on Sept 6, 1865.
Seventeen-yr-old Martha (middle name Evelyn or Eveline) is my gg-grandmother. She was born on 1 Aug 1963 (according to the 1900 census record) or perhaps 1 Aug 1860 (according to her death certificate). Her mother was Sarah Ann Oglesby. Martha married James M. Williams and they settled in Bibb Co., Ala and raised 10 children.
As far as the five children you listed for Dennis D. and Sarah in your message (Lewis, James, Mary, Reuben and Nancy) I have not came across them as yet in my research, but then I have not as yet found the 1860 and 1870 census records of Dennis and family.
