Andreas' History of the State of Nebraska - Military Rosters This website is well worth looking at. It names the Veterans residence as well as their nationality and in some cases where buried. Of the first 3 pages I came up with more states and countries than I can list here. Nationalities of Canada, Prussia, Ireland, Scotland, Germany, Sweden, England, Luxemboug, Switzerland, Wales, and more.
