Webinar Abstract: The presentation recounts the research involved in identifying New England and Mid-West Union soldiers whose burials in St. Augustine, Florida, were lost to time. The research begins with an 1865 stereogram photograph housed at the Library of Congress. Attendees will learn methods of researching record groups for men whose names were not known. This involves working within locality related sources to identify potential men, and then verifying them through other documentation. A case study illustrates the methods and highlights some of the documentation used to solve this research problem and to connect these men to their families.
