I am researching these families, too! I believe that Frederick Hurn died during the Civil War. He was awaiting execution for desertion when he contracted small pox and died of the disease. I will need to pull my records, but I believe the source was his civil war file. I believe Frederick was born 1827 in McDonough County, IL. I am a descendent of Sarah Jane Hurn. I believe there is some record that indicates those veterans were buried in one location and then they were reburied in a different location. I believe my Sarah was born in Atchison and that her first husband was Robert S. Coyan her second husband was Charles Kelsey Finton.
