I believe this could be the family you are describing though the ages are quite off your description.
Mahaley Ahart married Joseph Brackett 13 Apr 1857 Roane TN
1880 census
Auglaize, Camden, Missouri, United States
Joseph Brackett 45 household, Mahala 39, Sarah E. 9, Katie M 6, Christopher C. 4, Bertha G. 2, Thos 4/12
next door
I believe that Jessie Mahala Ahart is the daughter of Adam Ahart and Mary Elizabeth Tune.
Hope this helps.
James J Crabtree 22 household Marina C 17, Joseph W 2, Walter 7/12
