Keziah is enumerated in the 1850 census only once; on 11 September 1850 in DeKalb County, Tennessee. (Her family was enumerated a second time on 1 November 1850 in Hot Spring County, Arkansas.) It appears she died between the two enumerations.
The 1850 census says she was born in North Carolina. Other researchers have said she was born in DeKalb County, Tennesse, but I have seen no documents that supports this as her place of birth.
