I have the following J. or Joseph Duran/Durand/Durant listings in Alabama units. My list is by no means complete. The numbers are the National Archives Box, Roll and Number. They may be useful if you visit the archives or one of their refional offices.
Joseph E. Duran, Co. I 4(Russe;;'s) Al. Cavalry, pvt.,
000374, 0013, 00001797
J. G. Durand, Co. D, 34th Al. Inf. pvt. 000374, 0013, 00001803
J. S. Durand, Co. D, 34th Al. Inf. pvt. 000374, 0013, 00001805 (I'll bet they were kin)
J. Durant, Co. I, 23rd Al Inf. pvt. 000374, 0013, 00001811
I don't know where these units were formed, but I'll bet some of the folks on Al. board will have an idea. They are very good and don't mind helping, if they know.
Good luck
