In the 1860 census for Kings River Caroll Arkansas they have :Jefferson Davis age 39
Catherine age 36
John Davis age 18
Aaron Davis age 14
Charles Y Davis age 11
Susan Davis age 9
Martha DAvis age 7
Mary H.Davis age 5
William Davis age 3
Sarah M Davis age 1
MatildaC.Merryfield age 12 (She was listed as a Domestic)

I found these while looking for my Jefferson Davis with a daughter named Martha.I don't believe these are mine because my Jefferson was married to a mary or so I've been told.I know there was another Jefferson Davis with a son also named Jefferson but don't have any info on him.
Hope this helps.
