The JPG is attached. Number 1 is the signature on the Vicksburg parole (1863). 2 (1882) and 3 (1867) are from marriage licenses. 4 (1873), 5 (1870), 6 (1869), and 7 (1869) are from land transfer documents.
I can confirm that 4-7 refer to J E Jones as James E Jones within the document. The name of the person being married in 2 & 3 is James Edward Jones. Are all of these the same person? Number 3 is not signed by the same person, but it represents the same person as number 2. Did someone other than the groom often sign marriage licenses?
