Thank you Greg. I don't have access to those books, I sure wish I did.
Here is his name:
Edgar Dykeman 14th Iowa Infantry Company G
The roster says he was buried in Columbus.
From the same Regiment and Company, I wonder if the books give any information on: Samuel Jenks, said in the roster to have been killed at Shiloh, but his name doesn't seem to be at the National Cemetery there.
