I just ran across a U.S. Headstone Application for Military Veterans for Joseph Melvin Hicks (b1892/93 - d1941) that was submitted by his brother, Taylor Hicks, in 1949. Your surmise that Jesse Hicks sold some of the land back to the prison must be true, because the warden of the federal prison had to sign off on the application that the headstone for Joe Melvin Hicks would be permitted in the cemetery. The document is attached. (Joe Melvin was my 1st cousin 2x removed. My grandmother Carrie Opal Sloan Stephens lived with and looked after his parents, Jesse and Paralee, before she married).
