A search at the above URL returned a Frederick Kohler
(with an alternate surname spelling of Colan). He was
from MI and died 1864.
Our Christian F. KOEHLER was in a Confederate prison
but it was not Andersonville. His later death could be
reasoned to have been from the health problems that
he encountered in prison, as he was never healthy after
that imprisonment.
