I have a William McDuffee(also listed as McDuffery on the Civil War roster).

10th TN Calvary Regiment-Co. G

Rank-Private
Age-18
Enlisted-Dec 8th (what year??)
Mustered-Jan 27th
Remarks-Died March 8, 1864

I'd like to know how he died. Is there any way to find this out? I looked on the death rolls and he isn't listed.

I am new at researching the Civil War and appreciate any help at going about this.

Thank you.
