Wilhelm(William) Frederic Damitz is buried in the Mt. Zion Cemetary just outside of Quincy, MO. This is in Hickory County. The records have him as William J Damitz for some reason but the b. 12/1/1841 and d. 12/5/1900 are a match. His daughter Hattie L. (b. 7/18/1875 d. 11/20/1891) is also buried in the same cemetary. It also has the following information:Co H, 88th Reg, Ill inf Civil War.
I'm not sure what information you are looking for. My wife is a descendent of his twin brother Frederic William.
