I am researching a Gavin/Gaven Morton who enlisted as a Private in Company D, 38TH Infantry Regiment Iowa, from Howard County Iowa (October 23, 1864). The 38Th was combined with the 34TH Infantry Regiment (January 1, 1865). Gavin was assigned to Company H in the 34TH. Is anyone aware of any photographs that are available for either of these regiments? I am doing this research as a gift for a friend and would like to include a copy of a photograph of either or both of these regiments even if Gavin is not in the image. Thank you for your help.
