Hello Tom, I did a search and could not find this soldier as having served in the 14th Michigan Infantry.

A Bradley Markham was the only Markham listed in the 14th, but he was 45 years old.

I could find no officers or enlisted men under that name as being in any Michigan Regiment.

I checked soldiers whose names began with C and P, I also checked for spelling variants of the last name.

Additionally I searched this name to see if his name would show up as serving in another state and had no luck.

Steve
