1st Lt Duncan A. McCallum's head stone is now at the Pleasant Valley Cemetery off Merritt Rd in Dallas County Texas. I was just there on
10/24/2012. I made a picture. The head stone does not look like it could be an original stone from 1862. My great - great grandfather
Peter and wife Violet are buried there along with three sons, John Thomas, Langdon C. and William A. J. and many of their children.
