No Delona Patterson, but:

D. M. Patteson,pvt., Co. D, 4(Russell"s) Al. Cav. pvt. Also listed as David N. (more than likely not you man)
D. M. Patterson, Co. I 1st Reg't Al. Inf.
D. N. Patterson, Co. G, 48th Al. Inf. In Corp. out pvt. Also listed as David M. (more than likely not your man)
Not much help.
Good luck
