All of the materials in this folder were in a folder among Neiman's papers labeled, "Roy Harris," even though most of the correspondence is with other individuals, mainly Johana Harris, who was the chairman of the music department at Inter-American University, San German, Puerto Rico. Johanna Harris often signed her correspondence as "Lady Jo."
Other correspondence in the file is with Lotta Herslein and Marilyn Crawford. Roy Harris appears to have been the husband of Johana Harris.
