Jacob 5-26-1863
Samuel S. 6-1-1863 (relative?)
Elizabeth 6-19-1863
Sarah 6-19-1863 (possibly Jacob's younger sister in 1860 census?)
Linn County is next to Macon County: Maybe the Macon jail is where Jacob was taken in March 1863?
But Mo. marriages lists Jacob Andrew "Fargason" & Elizabeth Catharine Robinson 4 July 1863 in Laclede County, so Elizabeth would not have been a Forguson yet, unless common-law.
