A Family History Center recently opened close to where I live. My great-great grandfather and his brothers emigrated to the US during the 1860s, according to "The History of Pottawattamie County from the Earliest Day to 1907," one of them arrived in Illinois in time "to view the martyred body of President Lincoln." They came here from Erfde via Canada staying for a time in Chicago before settling in Crescent, Pottawattamie Co., Iowa. Does anyone know what films I need to look at to find them? Mark
