Terry Reimer, Director of Research at the National Museum of Civil War Medicine, was kind enough to not only let me know that Darius Townsend was on Clara Barton’s rolls of missing soldiers, but he sent me a digital copy of the roll. Thank you, Terry!
The date on the paper reads May 1, 1866. You will see Darius under the list of missing Wisconsin soldiers. This means someone wrote to Clara Barton, looking for him. Notice his last name is spelled “Tounsend.”
These letters to Clara Barton are at the Library of Congress and the National Archives. I am going to search through what remains of those, which is not the thousands that were sent to her.
