Lindsley's Memorial Rolls show a D.H. Diffee, 27th TN. Inf. Co. F, who died in Jan or Oct. 1862. Oddly, the CWSS shows no D.H. Diffee.
I've seen mistakes in Lindley's rolls before. Could this possibly be John Diffee ? The only Diffee I see in Company F is a Lewis Diffee. Perhaps he is D.H. Diffee? Something doesn't add up.
