James, The only information I have on this regiment and family member, Co. G: Marcus A. Hatfield, is from the Regimental Muster Rolls held by the Adjutant General's Office of the State of Illinois, the Office's Regimental Report and gravestone for the above located in Garlough Cemetary, Pitchin Ohio. Sorry, I can't be of more help. I would like to see some of your information though, if that is possible.

Neil E. Hatfield
