Thank you Greg. That is what I have discovered in my searching also. I was thinking perhaps there was some other way of finding them, or some other place they may have been taken, especially Dykeman, who did not die in battle so his grave should have been well marked. His brother died in St. Louis around the same time and his grave can be easily located.
I was also hoping Jenks would be found as well somewhere, since his army retained possession of the Shiloh field, I'd think it would be fairly safe assume he was buried in a marked grave, at least originally or at least would have been listed in the Roll of Honor.
From the roster of the Iowa 14th Infantry, Company G:
Jenks, Samuel W. Age 19. Residence Story County, nativity Indiana. Enlisted October 9, 1861. Mustered November 2, 1861. Promoted Fifth Corporal. Killed in action April 6, 1862, Shiloh Tennessee.
Dykeman, Edgar. Age 24. Residence Redman, Tama County, nativity New York. Enlisted October 9, 1861. Mustered November 2, 1861. Missing in action April 6, 1862, Shiloh, Tennessee. Promoted Fifth Corporal April 12, 1863. Died of chronic diarrhoea July 19, 1863, Columbus, Kentucky. Buried in( .. )Cemetery near Columbus, Kentucky.
Ok, can we try for one more?
Thomas Snelling of the same Regiment and Company was killed at Fort Donelson during a charge on the breastworks. His body was recoverd and buried on the field that evening. I find no official burial place for him either. Any mention of him in the Roll of Honor?
From the roster:
Snelling, Thomas. Age 26. Residence Story County, nativity Ohio. Enlisted October 9, 1861. Mustered November 2, 1861. Killed in action February 13, 1862, Fort Donelson, Tennessee.
