I note that there is a Oscar Bartlett GAR in Michigan. Is the the soldier who was a Sgt. in Co. C 22 Mich? This soldier died in Danville, Virginia on January 25, 1864 of Small Pox while a prisoner of war. He was admitted to the hospital on January 7, 1864. He is not listed as buried in the Nation Cemetery here, but is probably one of the unknown.
