However, in his lifetime Hale visited neither Mackinac nor Michigan. In his 1893 and 1900 reminiscences, E.E. Hale stated that ‘To write the story of “The Man Without a Country” and its sequel, “Philip Nolan’s Friends,” I had to make as careful a study as I could of the history of the acquisition of Louisiana by the United States.’ In Hale's many publications, he described other locations that he had never seen. He was able to do this because he had extensive libraries and publications available to him. Hale was a writer, editor, and Unitarian minister who resided in and traveled throughout New England; he visited Texas once. The Mission House was listed on the National Registry of Historic Sites in 1971, and was listed in the Michigan Registry of Historic Sites in 1993. It is Michigan Historic Site #SO313.
