Civil War records (1) put his surname a Jelany- or Jean S. or Jelang at different times so,  it is hard to say if it Jean Baptiste and/or Ghislain, the two sons of Sylvere Taburiaux of military age, 25 and 22 years old in 1861. Or if Jabos S is another one, not yet recorded.

Jacob S, as recorded in the 1870 Gordon census, Georgia married Elizabeth Townsend, and they and all their children are buried at White Cemetery, Gordon County. 

Jean Baptiste is recorded(2)  in 1864 as Tabadaux J.B.,  28 yrs Farmer from France as a being not in military service.
